Answer:
x = +-12
Step-by-step explanation:
x^2 -144 =0
(x-12) (x+12) =0
using the zero product property
x-12=0 x+12 =0
x=12 x=-12
Answer:
y = -5x - 8
Step-by-step explanation:
Take the points (-5,-4) and (0,-3) plug them into this formula to get the slope.
Now plug in your points
Since you're slope is 1/5 the slope of the perpendicular line is going to be the totally opposite -5 is the slope of the perpendicular line.
Now plug in -5 and the point (-2,2) into y = mx + b to get the y-intercept
2 = -5(-2) + b (b represents the y-intercept)
2 = 10 + b (subtract 10 from both sides)
-8 = b
The perpendicular line looks like this y = -5x - 8

Answer:
surface area of cube=6×side²
surface area of cube=6×(8ft)²
surface area of cube=384ft²
Answer:
=−4√2
I got this when simplified.
Yes, because by the triangle inequality, a triangle can be formed from three segments of which the sum of the lengths of the two shorter ones exceed the longest segment.
Here we have 36+48=84 > 60, so the three segments form a triangle.
Since the ratio of the sides are 36 : 48 : 60 form the ratio of 3:4:5, which is exactly the ratio of a right triangle, we conclude that the triangle is a right triangle.
