The area of real backyard is 72 square meters.
Step-by-step explanation:
Given,
Length of rectangular backyard = 8 cm
Width of rectangular backyard = 4 cm
According to scale;
2 cm = 3 m
1 cm = 
Real length of backyard = 8*1.5 = 12 m
Real width of backyard = 4*1.5 = 6 m
Real area of backyard = Length * Width
Real area of backyard = 12*6 = 72m²
The area of real backyard is 72 square meters.

F(x) = 8 - 10x
g(x) = 5x + 4
Finding (fg)(-2).
First let us find fg(x), this is the same as f(g(x))
f(g(x))
f(5x + 4)
Recall, f(x) = 8 - 10x, therefore f(5x + 4) would be such that anywhere we see x in the f(x), we replace it with 5x + 4
f(x) = 8 - 10x
f(5x +4) = 8 - 10(5x + 4)
= 8 - 50x - 40
= -50x + 8 - 40
= -50x - 32
f(g(x)) = fg(x) = -50x - 32
fg(-2) = -50*(-2) - 32 = 100 - 32 = 68
Therefore fg(-2) = 68
I hope this helped.

Yes totally friend, I totally hear you on that!! ^-^ Good luck for your weekend!!!
Step-by-step explanation:
9, 14, and 22.
The formula for checking if a triangle will work is side a + side b > side c.
The only one that works is 9, 14, and 22.
A because complementary angles means 2 angles that add together to equal 90 degrees and it's possible for both angles to be 45.
