Work out 1.6 X 10⁴ + 0.8 X 10⁴.

math work

Step-by-step explanation:

1. 100a²-25b² [use : a²-b² formula : (a+b)(a-b)]

=> 25(4a²-b²)

=> 25(2a-b)(2a+b).

2. m³+125 [use : a³+b³ formula: (a+b)(a²-ab+b²]

=> m³+5³ => (m+5)(m²-5m+25).

3. 8a³-64b³ [use : a³-b³ formula: (a-b)(a²+ab+b²]

=> 8(a³-8b³) => 8(a-2b)(a²+2ab+b²)

4. x² - 8x + 12 [middle term breaking)

=> x²-2x-6x+12 => x(x-2)-6(x-2) => (x-2) (x-6)

5. b² - 6b - 27 [ middle term breaking]

=> b²-9b+3b-27 => b(b-9)+3(b-9) => (b-9)(b+3).

hope this helps you.

Step-by-step explanation:

Multiply each number by 3.

Answer:

y = -2x + 6

Step-by-step explanation:

Slope intercept form: y = mx +b

y + 4 = -2(x - 5)

y + 4 = -2x  + 10

y = -2x + 10 - 4

y = -2x + 6

Answer:

1, 7, 17, 31

Step-by-step explanation:

2(1)² + 1 - 2 = 3-2 = 1

2(2)² + 1 - 2 = 9-2 = 7

2(3)² + 1 - 2 = 19-2 = 17

2(4)² + 1 - 2 = 33-2 = 31

Step-by-step explanation:

let tye number Ahmed thinks be x.

so, a/q

the equation is,

→ 2x/5 = 4

→ 2x = 4×5 = 20

→ x = 20/2

→ x = 10

therefore, he thinks the number 10.

hope this answer helps you dear!

Answer:

10

Step-by-step explanation:

I'm doing it from the end.

if the answer is 4, you have to multiple it by 5 and then divide it by 2

4 x 5 ÷ 2 = 10

10 multiple by 2 is 20 and 20 divided by 5 is 4 so

10 is correct answer

A characteristic of a deferred payment plan is that the item purchased is used as collateral until the balance is paid in full.

A deferred payment plan is a form of credit purchase, a way to pay for an item in arrears. The payment is usually divided into several installments, which are distributed over a certain period of time. Interest and fees are often added, which in the end makes the purchase considerably more expensive than if you had paid in cash.

Thus, through this payment system, the asset is delivered to the buyer before the payment is completed, thereby constituting the asset itself as an enforceable guarantee of payment compliance.

Answer:

128 sq. ft.

Step-by-step explanation:

The outer sides of the walkway will have a length of 20 feet and the breadth will be 16 feet

The area of the pool along with the walkway will be 20 × 16 = 320 square feet.

Area of the pool without the walkway will be 16 × 12 = 192 square feet.

Therefore area of the walkway will be

352 - 216 = 128 square feet.

The cost per unit of the auto shop function is the slope of the function

87 represents the slope and the cost per tire purchased

The function is given as:

A linear function is represented as:

[tex]\mathbf{C(t) = mt + b}[/tex]

Where:

m represents the slope or the unit rate.

So, by comparison:

This is an equilateral triangle.

We see that all 3 angles are equal,  so all sides are equal also.

So 2x - 6 = 10

2x = 16

x = 8.

Answer:

Step-by-step explanation:

If I am correct the triangle has equal sides and I think you're trying to find x. So 10=2x-6 and then solve. Once you get the x (assuming you know how to get it) plug it into the equation (of 2x-6) and get the remaining number. (For example: if x=2 then 2x2-6, then you solve: 2x2=4 4-6=-2) I don't know if you want the answer though...

(depends if you want x or the rest)

Hello!

To find the mean, we must add all the terms in the dataset and divide by how many there are.

35+26+31+16+21+23+27+30+26+17+19+27=450

There are 12 terms in the dataset, so we divide by 12:

37.5

So the mean of this set is 37.5.

Answer:

x = 2

Step-by-step explanation:

5(x-4) =-10

Distribute 5 by multiplying x and -4 by 5

5x - 20 = -10

Add 20 to both sides

5x - 20 + 20 = -10 + 20

5x = 10

Divide both sides by 5

5x ÷ 5 = 10 ÷ 5

x = 2

Step-by-step explanation:

its very easy correct me if im wrong brainliest btw

Step-by-step explanation:

You need to find the total number of students the pie chart will represent:

17 + 35 + 38 = 90

So you know, 360° represents 90 people

You can then find out the angle for each person: 360 ÷ 90 = 4

Each person is 4°

a)

1. 17 people took French so you would do 4° × 17 = 68°

2. 35 people took German so you would do 4° × 35 = 140°

3. 38 people took Italian so you would do 4° × 38 = 152°

b)

17 out of 90 people chose french so the probability would be 17/90
