Answer:

a. False

b. True

c. True

d. False

Step-by-step explanation:

a. Is false because it says the equivalent ratios of centimeters and feet. When it is comparing centimeters and inches

b. Is true because the unit rate in this double number line is 2.54 centimeters per inch

c. Is true because it shows on the double number line that 6 inches is equal to 15.54 centimeters

d. Is false, although the fact that 0.039 inches are in a centimeter is true, it does not show that rate in the double number line

I hope this helps :)

Fill in the blank. (5x)2 a0x2

Yuki888 [10]

Answer: $a_0=25$

Step-by-step explanation:

It is given that, $(5x)^2=a_0x^2$

We need to find the value of $a_0$

As $(5x)^2=a_0x^2$

Solving LHS

$25x^2=a_0x^2$

Now comparing the coefficients of $x^2$

In LHS the coefficient of $x^2$ is 25

In RHS the coefficient of $x^2$ is $a_0$

It implies that, $a_0=25$

So, the value of $a_0$ is 25.

HELP ME!! plz? Combing like terms.

Bad White [126]

T: 8x+19

7x-2(4-2x)+6(5-x)-x+2-(6x+5) = 7x-8+2x+30+6x-x+2-6x-5 = 8x+19

Y: 56-8x

9-(-2-3x)+4(-x+6)-x+12-3(2x-3) = 9+2+3x-4x+24-x+12-6x+9 = 56-8x
