Answer:
Step-by-step explanation:
The area of a triangle is base*height/2
So one triangle is 2*4/2=4
Multiplied by 4 sides, 4*4=16
Finally the base is a square, so 2*2=4
Therefore the entire shape is 16+4=20 square feet
The result of the exponential expression is 81
<h3>Indices expressions</h3>
Indices are written in term of exponents
According to the expoenent law of indices
a^4 = a * a * a * a
Given the expression
(-3)^4
This means the product of -3 in four places. Mathematically
(-3)^4 = -3 * -3 * -3 * -3
(-3)^4 = 9 * 9
(-3)^4 = 81
Hence the result of the exponential expression is 81

Y = -6x - 15
We’re already at -3 (y) and the slope is negative so the y intercept is < -3. X is -2 and we need to find the y when x is 0. -2 is 2 away from 0 and 6 (the slope) times 2 is 12. -3 - 12 = - 15
