No.
0.3^4 or 0.3x0.3x0.3x0.3= 0.0081
0.9^2 or 0.9x0.9=0.81
These are not equivalent.
A^2 + 31 = 155 - I squared each of b and c for those numbers
a^2 = 155 - 31
a^2 = 124
a = 4 * sqrt(31)
The correct answer is the first one
Answer:
Step-by-step explanation:
(-1,7), (0,5), (1,3)
and
(0,-3), (2,5), (4,13)
You basically have a triangle and a rectangle. seperate the two at first, the rectangle's area is 32 since 8*4=32
the area of a triangle is half of it's base times width. so 3*5=15/2=7.5
add 7.5 and 32 to get 39.5
