Hello from MrBillDoesMath!

Answer:

w = 5

Discussion:

48 = 2 (2w) + (4 + 2w)2 =>

48 = 4w + 4*2 + (2w)*2 =>

48 = 4w + 8 + 4w => as 4w + 4w = 8w

48 = 8w + 8 => subtracting 8 from each side

48 - 8 = 8w => divide both sides by 8

(48 -8 )/8 = w =>

40/8 = w =>

w = 5 =>

Check: 2(10) + ( 4 + 2*5)*2 = 20 + 14*2 = 20 + 28 = 48

Thank you,

MrB

You can change 24.5% by moving the decimal point
24.5%=.245

Express the answer in standard form.

Natali [406]

Answer:

$-2x^{2} +8x-10$

Step-by-step explanation:

Standard form is basically where the degrees of the terms are in descending order.

First, let's distribute the negative sign to the terms in the second parentheses:

$-(3x^{2} -5x+3) = -3x^{2} +5x-3$

Now, we can just combine like terms with the terms from the first parentheses:

$x^{2} +3x - 7 - 3x^{2} +5x-3 = -2x^{2} +8x-10$

So, our answer is: $-2x^{2} +8x-10$

Sati [7]

Answer:

Step-by-step explanation:

WE willl solve the question for the following equation $-8c-10+4c=-6c+8$

1. Add 8c on both sides

$8c-8c-10+4c = 8c-6c+8$

$-10+4c = 2c+8$

2. Add 10 on both sides

$10-10+4c = 10+2c+8$

$4c = 2c+18$

3. Substract 2c on both sides

$4c-2c = 2c+18-2c$

$2c =18$

4. Divide both sides by 2

$\frac{2c}{2}=\frac{18}{2}$

$c=2$

Then, the equation is solved.
