Answer: 160 square inches
if the block is cut after it’s been painted, two sides with the same measurements don’t have glitter on them. you find the area of the one rectangle and multiply it by 2 as follows:
A = length • width
A = 10 • 8 = 80
area that needs to be covered = 80 • 2 = 160 square inches
Step-by-step explanation: I just knowww
The equation 5/2 - x + x - 5/x + 2 + 3x + 8/x^2 - 4 = 0 is a quadratic equation
The value of x is 8 or 1
<h3>How to determine the value of x?</h3>
The equation is given as:
5/2 - x + x - 5/x + 2 + 3x + 8/x^2 - 4 = 0
Rewrite as:
-5/x - 2 + x - 5/x + 2 + 3x + 8/x^2 - 4 = 0
Take the LCM
[-5(x + 2) + (x -5)(x- 2)]\[x^2 - 4 + [3x + 8]/[x^2 - 4] = 0
Expand
[-5x - 10 + x^2 - 7x + 10]/[x^2 - 4] + [3x + 8]/[x^2 - 4] = 0
Evaluate the like terms
[x^2 - 12x]/[x^2 - 4] + [3x + 8]/[x^2 - 4 = 0
Multiply through by x^2 - 4
x^2 - 12x+ 3x + 8 = 0
Evaluate the like terms
x^2 -9x + 8 = 0
Expand
x^2 -x - 8x + 8 = 0
Factorize
x(x -1) - 8(x - 1) = 0
Factor out x - 1
(x -8)(x - 1) = 0
Solve for x
x = 8 or x = 1
Hence, the value of x is 8 or 1

Answer:
===========================
The amount of simple interest is:
- Interest = Loan * rate * time
or
Given:
- P = $60000, r = 6.5%, t = 12 years
Substitute and calculate:
- I = 60000*(6.5/100)*12 = 46800
The matching choice is D.
1) let say a + b = -16
than 3times larger equal smaller can be represent by 3a = b.
now sub 3a into the b of the equation and simplify you will get 4a = -16 where a = -4 and a is the larger nymber since b will =-12 which is smaller than a
(2w-8)+2L because there are 2 sides for the width 2*4=8 so 2w -8 plus 2L
