Answer:

a) 8²

b) 2⁴ and 5⁴

Step-by-step explanation:

The power of a number is the base together with the exponent of the number.

The given expresion is

( {8}^{2} )^{3}

We can rewrite this as:

{8}^{2}  \times  {8}^{2}  \times  {8}^{2}

Over here the power being multiplied is

{8}^{2}

Also, the powers being multiplied in

( {2}^{4} )( {5}^{4} )

are 2⁴ and 5⁴

the perimeter of a rectangle is 56 m. if the width were doubled and the length were increased by 8 m, then the perimeter would b
Natasha2012 [34]
----------------------------------------------------------------
Define x and y:
----------------------------------------------------------------
Let the length be x.
Let the width be y.

----------------------------------------------------------------
Formula:
----------------------------------------------------------------
Perimeter = 2(Length + Width)

----------------------------------------------------------------
Construct equations and solve for x and y:
----------------------------------------------------------------
2x + 2y = 56            ---------------------- (1)
2(x+8) + 4y = 82     -----------------------(2)

----------------------------------------------------------------
From equation 1:
----------------------------------------------------------------
2x + 2y = 56
x + y = 28
x = 28 - y

----------------------------------------------------------------
From equation 2:
----------------------------------------------------------------
2(x+8) + 4y = 82 
2x + 16 + 4y = 82
2x + 4y = 66
x + 2y = 33

----------------------------------------------------------------
Substitute x = 28 - y into equation 2:
----------------------------------------------------------------
x + 2y = 33
(28 - y) + 2y = 33
28 - y + 2y = 33
y = 5

----------------------------------------------------------------
Substitute y = 5 into equation 1:
----------------------------------------------------------------
x = 28 - y 
x = 28 - 5
x = 23

----------------------------------------------------------------
Find Length and Width
----------------------------------------------------------------
Length = x = 23 m
Width = y = 5m

----------------------------------------------------------------
Answer: Length = 23m and Width = 5m
----------------------------------------------------------------

Slove for x 3(x+1)=-2(x-1)-4
Andrews [41]

Step-by-step explanation:

3(x+1)=-2(x-1)-4

3x+3=-2x+2-4

by combining like terms on one side and unlike term by other side

3x+2x=2-4-3

5x= -5

x= -5/5

x=-1
