Answer:

8 Inches

Step-by-step explanation:

The length would be w+5, making your equation (5)(w+5)(w)=120, which can be simplified to 5w²+25w-120=0. Then take out a GCF of 5, giving you 5(w²+5w-24)=0. Find the factors and get (w+8)(w-3). Your solutions are -8 and 3. -8 can be taken out, so the final answer is 3. Then you plug it back into the length, so 3+5 is 8.

If f(x)=| x-2 |, then find f(-3)

GenaCL600 [577]

The value of f(-3) is 5.

In order to find this answer, we are going to input -3 in for x (this is what the notation f(-3) means).

f(x)=| x-2 |

f(-3)=| -3 -2 |

f(-3)=| -5 |

Now we have to take the absolute value.

f(-3) = 5
