Answer: -1

Raising one exponential expression to another exponent means you multiply the exponents together. We have 5*5 = 25 as the new exponent.

So we end up with (-1)^25 = -1

The rule I'm using is that -1 to any odd whole number power is going to result in -1. If the exponent was even, then -1 to that power would be 1.

So in short, the rule says

(-1)^n = -1 if n is an odd whole number

(-1)^n = 1 if n is an even whole number

If the m∠1=123° m ∠ 1 = 123 ° and m∠2= (2x+7)° m ∠ 2 = ( 2 x + 7 ) ° , determine the value of x that supports l∥m l ∥ m . Show y
Georgia [21]

Answer:

25

Step-by-step explanation:

Let us assume that m<1 nad m<2 are supplementary. Since the sum of supplementary angles is 180degrees, hence;

<1 + <2= 180

123+2x+7 = 180

130+2x = 180

2x = 180 - 130

2x = 50

x = 50/2

x = 25

Hence the value of x is 25

The length of a rectangle is 2x – 3 feet, and the width is 5 feet. What is the area of the rectangle in square feet?
dimaraw [331]
The area of a rectangle is length times width or base times height

so 5 times 2x-3

if you multiply them together 5(2x-3) you would get 10x-15

there is no value of x

so the area would be 10x-15ft^2
