21 because you turn the 5 yards in to feet which is 15, then you add 15+4+2=21

Easiest way to get the surface area of the lateral square pyramid is by using the formula:

a = Base edge = 646 ft
h = Height = 350 ft
Using the formula:

[tex]A_{L} = 6.15335×10^{5} square feet
[tex]A_{L} = 615335<span> square feet</span>
Answer:
y = mx + b
Where m is the slope and b is the y-intercept.
To do this we just solve for y.
Subtract 6x from both sides.
-2y = 10 - 6x
Divide both sides by -2.
y = -5 + 3x
m=3
The line has a slope of 3.
Answer:
B
Step-by-step explanation:
Well first exponiantial growth, always increases. so
The first one goes
which we can see that doesn't apply
The second one goes

the third one goes

the fourth one goes

so the only options are the second one and the fourth one, but when the exponent is negative the function should decrease so the answer is B
