Answer:
x to the third power is x cubed or x^3.
3/7. if you make them equivalent fractions it would be 30/70 or 14/70. 30/70 is bigger.
(10x+5)4 = 30x + 3x + 6x +30
40x + 20 = 39x + 30
X = 10
perimeter of the square= 420
perimeter of the triangle= 420
Answer:

Step-by-step explanation:
we have
Line 1

Equation in slope intercept form
The slope is equal to

Line 2


Equation in slope intercept form
The slope is equal to

we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)
so

substitute


Answer:
the answer would be C.
