Answer:

Step-by-step explanation:

Like terms are ones with the same variable (or set of variables). Here, any x-terms are "like" terms. They are combined by adding their coefficients.

  4x +4x +4x +4x = x(4+4+4+4) = 16x

  -7x +4 +3x = x(-7+3) +4 = -4x +4

  3x +5x +8 = x(3+5) +8 = 8x +8

  4x +4x = x(4+4) = 8x

Answer:Answer:

The answer is x^2 + x =420

Step-by-step explanation:

It is given that

The product of two consecutive integers is 420

Le x be the first number, then

second number is the next consecutive number of x which is (x +1)

The product of these numbers can be written as

x (x + 1) which is equal to 420

x (x + 1)  = 420

x^2 + x = 420

So the quadratic equation is

x^2 + x = 420

Answer:

No, you are not correct.

It should look like this:

                              Prefer colorful decorations      Prefer neutral decorations

Pay attention                           20                                                  25

to fashion

Do not pay

attention to                              72                                                      33

fashion

Step-by-step explanation:

33 is 22% of 150. In the question it states that 70% of people do not pay attention to fashion. We need to find the other 48% here. In order to do that we multiply .48 by 150. That gets us 72. To check that answer you can add both 72 and 33 and then divide by 150, which gets 70%.

To get the amount of people that prefer neutral decorations and pay attention to fashion we need to add up 20 + 72 + 33 and that equals 125. Next, we take 150 and minus 125 of it to get 25.

Hope this helps!!

Answer:

[tex]\sqrt{15}[/tex]

Step-by-step explanation:

[tex]\cos(\theta)=\frac{1}{4}[/tex] is given.

My attempt will to be to use the Pythagorean Identity:

[tex]\cos^2(\theta)+\sin^2(\theta)=1[/tex]

[tex](\frac{1}{4})^2+\sin^2(\theta)=1[/tex]

[tex]\frac{1}{16}+\sin^2(\theta)=1[/tex]

Subtract 1/16 on both sides:

[tex]\sin^2(\theta)=\frac{15}{16}[/tex]

We have the following quotient identity:

[tex]\frac{\sin^2(\theta)}{\cos^2(\theta)}=\tan^2(\theta)[/tex]

[tex]\frac{\sin^2(\theta)}{\cos^2(\theta)}=\frac{\frac{15}{16}}{\frac{1}{16}}[/tex]

Multiply the numerator and denominator by 16. This is multiplying the fraction by 1 so this doesn't change the value of the fraction.

[tex]\tan^2(\theta)=\frac{15}{1}[/tex]

[tex]\tan^2(\theta)=15[/tex]

Square root both sides:

[tex]\tan(\theta)=\pm \sqrt{15}[/tex]

Since we are in the first quadrant then all 6 trigonometric functions are positive there so the answer is [tex]\sqrt{15}[/tex].

Answer:

35 inches

Step-by-step explanation:

multiply length value by 12

Answer:

-16

Step-by-step explanation:

2 + 2(-3)²

Exponents come first, so we would multiply -3 by itself.

2 + 2(-9)

Next is Multiplication, so we multiply 2 and -9 together

2 - 18

We subtract 18 from 2 to get,

-16

Answer: 0.20 Ω

Step-by-step explanation:

From the question, we are informed that a multi-cab starter motor has a current of 60.0 A and a voltage of 12 V. The resistance of the starter motor will be calculated thus:

Current (I) = 60.0A

Voltage (V) = 12V

Resistance = Unknown

Since Voltage = Current × Resistance

Therefore, Resistance = Voltage / Current

= 12/60

= 0.20 Ω

The resistance of the motor is 0.20 Ω

The resistance of the starter motor if a multi-cab starter motor has a current of 60.0 A and a voltage of 12V is 0.2 ohms

Based on the given question, for us to get the resistance of the starter motor, we will need to use Ohm's law.

According to the law, the current I passing through a conductor at constant temperature is directly proportional to the voltage "V". Mathematically;

V = IR

V is the voltage = 12V

I is the current = 60.0A

R is the resistance

Substitute the given parameters into the formula as shown:

12 = 60 R

R = 12/60

R = 1/5

R = 0/2

Hence the resistance of the starter motor if a multi-cab starter motor has a current of 60.0 A and a voltage of 12V is 0.2 ohms

Step-by-step explanation:

Given: m∠A = m∠C = 90° and  AD = CB

Prove: ΔABD ≅ ΔCDB

--------------------------

Since angles A and C are right angles, ΔABD and ΔCDB are right triangles

DB is common side, so

As per HL Postulate if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent

The correct answer is:

Option 2: [tex]\frac{4}{6} = \frac{20}{30}[/tex]

Step-by-step explanation:

Given that

Width of picture = 4 inches

Length of picture = 6 inches

Now

Width of poster = 20 inches

Length of poster = 30 inches

The proportion of the picture will be:

[tex]\frac{width}{length} = \frac{4}{6}[/tex]

Similarly the proportion of poster can be written as:

[tex]\frac{width}{length} = \frac{20}{30}[/tex]

Both proportions when combined can be written as:

[tex]\frac{4}{6} = \frac{20}{30}[/tex]

Hence,

The correct answer is:

Option 2: [tex]\frac{4}{6} = \frac{20}{30}[/tex]

Answer:Roots of a number indicates value where function will be zero. If an equation let's say

y = f(x) = x^2 -3x + 2 has two roots x = 1 and x =2 . Now if you will draw the graph, line will cross x-axis at 1 and 2 indicating y will become zero at 1 and 2. But if any equation has imaginary roots implies y will be never be zero for any real value of x and as we do not show imaginary number on a Cartesian plane we cannot make y =0 hence graph will never touch x-axis.
