Answers
Answer:
[tex] x = -2 [/tex] or [tex] x= -3 [/tex]
The solution is real.
Step-by-step explanation:
x^2 + 5x + 6 = 0
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-5 \pm \sqrt{5^2 - 4(1)(6)}}{2(1)} [/tex]
[tex] x = \dfrac{-5 \pm \sqrt{25 - 24}}{2} [/tex]
[tex] x = \dfrac{-5 \pm \sqrt{1}}{2} [/tex]
[tex] x = \dfrac{-4}{2} [/tex] or [tex] x = \dfrac{-6}{2} [/tex]
[tex] x = -2 [/tex] or [tex] x= -3 [/tex]
The solution is real.

The angles of a triangle are A, B and C.
Angle A is three times as big as angle B.
Angle B is half the size of angle C.
What is the size of angle A?
Answers
Answer:
∠A = 90°
Step-by-step explanation:
∠A = 3∠B
∠B = 1/2 × (∠C), this can also be written as ∠C = 2∠B
∠A + ∠B + ∠C = 180, because there are 180° inside a triangle
Write angle A, B and C in terms of angle B:
3 ∠B + ∠B + 2 ∠B = 180
Simplify:
6 ∠B = 180
∠B = 180 ÷ 6 = 30°
Work out angle A:
∠A = 3∠B = 3 × 30°
∠A = 90°

Answer:
x = 6.4
Step-by-step explanation:
Step 1: Divide both sides by 4.
[tex]\frac{4x}{4}=\frac{25.6}{4}[/tex] [tex]x = 6.4[/tex]Step 2: Check if solution is correct.
[tex]4(6.4)=25.6[/tex] [tex]25.6=25.6[/tex]Therefore, x = 6.4.
Answer:
4x = 25.6
4x = 256 / 10
x = 256 / (10×4)
x = 64 / 10 (256 ÷ 4 = 64)
x = 6.4
so, answer is 6.4 .

If a square has a perimeter of 36cm how long is each side of the square
Answers
Answer:
9 cm
Step-by-step explanation:
→ Remember how many sides a square has
4
→ Divide it by the perimeter
36 ÷ 4 = 9
Step-by-step explanation:
you know what a square is ?
it is a closed shape with 4 sides.
all 4 sides are equally long.
all 4 inner angle are 90 degrees.
you know what a perimeter is ?
it is the circumference, the whole way one time around the shape, around the outline of a given structure.
if you don't know the terms, for heaven's sake, please ask your teacher, your friends, your parents or us here directly.
don't wait. don't be afraid or ashamed.
because this here is an extremely simple problem to solve, once you understand the words used.
so, as per the explanations, the perimeter of a square is the sum of the lengths of all sides. and because all sides are equally long, this means the perimeter is simply 4 times the length of one side.
36 = 4×side
side = 36/4 = 9cm
so, each side of the square is 9cm long.

what is the slope of a line parallel to the line on the graph?
Answers
Answer:
3/4
Step-by-step explanation:
To find the slope of a line parallel to this line, we first need to find the slope of this line. Using rise/run, you get that the slope is 6/8 which simplifies to 3/4.
The slope of any two parallel lines always is the same so the slope of a line parallel to the one given would be 3/4.

Answers
Answer:
A) Volume of prism: 4 * 8 * 9 = 288 cubic units
B) Area of shaded base: 4 * 8 = 32 squared units
Volume of prism: 32 * 9 = 288 cubic units
Step-by-step explanation:
The volume of a prism can be calculated by multiplying its length, width, and height. The length of the prism is 8, the width is 4, and the height is 9. Thus, we get 8*4*9 = 288 cubic units. (cubic units because we are dealing with volume)
The area of the shaded base can be found by multiplying its length by its width. The length is 8 and the width is 4. Thus, 4*8 = 32 squared units (squared because we are dealing with area)
The volume of the prism using the area of the shaded base can be calculated by multiplying the area of the shaded base by the height, this is because the area of the shaded base is already the length * width and thus we only need to multiply by the height which is 9. Therefore we get 32 (area of shaded region) * 9 (height) = 288 cubic units.

The thermostat for a house is set to 70°F, but the actual temperature may vary by as much as 4°F. Use an
absolute value inequality to find the range of possible temperatures in the house.
The range of possible temperatures in the house (in degrees Fahrenheit)
Answers
Answer:
Step-by-step explanation:
74’F
Answer:
The range of possible temperatures in the house (in degrees Fahrenheit) is 60° F ≤ T ≤ 74°F
Step-by-step explanation:
To Find:
The range of possible temperatures in the house
Solution:
Given:
Thermostat is set to 70 °
Also actual temperature may by a much of 4°
If the temperature is 4°F lower, and actual temperature = 70°- 4° = 66° F
If the temperature is 4°F higher, actual temperature = 70°+4° = 74°
Therefore, The range of possible temperatures in the house (in degrees Fahrenheit) is 60° F ≤ T ≤ 74°F
