The answer is D. 200m = 2cm. That's because to get from meters to centimeters, you need to multiply by 100. 200 * 100 is not 2, therefore D is the answer.

Ax+3=23 if a=0 plz help

VladimirAG [237]

Answer:

x = $\frac{23}{a}$

Step-by-step explanation:

Given equation is,

ax + 3 = 23

To solve this equation for the value of x isolate the variable 'x' on the one side of the equation.

Step 1,

Subtract 3 from both the sides of the equation.

ax + 3 - 3 = 23 - 3

ax = 20

Step 2,

Divide the equation by a,

$\frac{ax}{a}=\frac{23}{a}$

x = $\frac{23}{a}$

Therefore, x = $\frac{23}{a}$ will be the answer.

Factor the polynomial.

Degger [83]

It is answer choice A because you have to take the the GCF of each number which is 2x. Then if you were to divide the numbers by 2x you would put those numbers in the brackets.
$2x( x^{2} +2x+4)$ because $2x^3/2 x = x^{2}$ and $4 x^{2} /2x = 2x$ and $8x/2x = 4$
