Answer:
- 13
Step-by-step explanation:
To evaluate (g ○ f)(3), evaluate f(3) then use this value to evaluate g(x)
f(3) = 3 - 7 = - 4, then
g(- 4) = 4(- 4) + 3 = - 16 + 3 = - 13
Answer:
x - 7
Step-by-step explanation:
7 - 1= 6
1 - 7= -6
-1 + 7= 6
7 + (-1) =6
The square mural in Olivia's classroom has dimensions x by x.
Then she paints a mural of dimensions: x+5 (the length) by x-2 (the width).
Thus the second mural (the hallway mural) has the shape of a rectangle with dimensions (x+5) by (x-2), so the area of the second mural is
(x+5)(x-2).
<span>
each side of the classroom mural is 7 feet means that x = 7 ft,
</span>
thus the area of the hallway mural is :
(x+5)(x-2)=(7+5)(7-2)=12*5=60 (square feet)
Answer:
<span>C. (x + 5)(x – 2); 60 square feet</span>
