Answer:

1. QR = HI

2. angle W and angle T

3. WB = UV

Step-by-step explanation:

It could me fill in the part of the proof, since I notice on all of them they only mark one or two of the congruencies on the shapes. I'm not really sure of 3's answer.

Hope this helped somewhat and good luck

Given f(x) = x − 7 and g(x) = x2 . Find g(f(−1)).

ivann1987 [24]

Answer:

Step-by-step explanation:

$g(f(-1))$ can be found by first finding $f(-1)$ then taking that result and putting it into the function $g$ .

$f(-1)$ means we are going to take the expression $x-7$ and evaluate it for $x=-1$ :

$-1-7$

$-8$

So $f(-1)=-8$ .

So we have this so far:

$g(f(-1))=g(-8)=(-8)^2=64$ .

$g(-8)$ was found by replacing $x$ in $x^2$ with $-8$ .

Three sides of a quadrilateral are the same length, g, The length of the fourth side is 7 inches,

Ulleksa [173]

Answer:

Step-by-step explanation:

Let s represent the length of each of the three sides mentioned. The length of the fourth side is 7 inches. Adding the lengths of the four sides together yields 10 inches: g + g + g + 7 = 10 (inches)

Then 3g + 7 = 10, or 3g = 3, or g = 1.

This equation is OK, but there's no solution, since 3g or just 3 is less than 7. With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.
