Nine billion, three million, eight hundred forty thousand, one hundred sixty five
Answer:
x=2
Step-by-step explanation:
8x+4=20
Subtract 4 from each side
8x+4-4 = 20-4
8x =16
Divide by 8
8x/8 = 16/8
x=2
Answer:
Step-by-step explanation:
It's correct. Clear
-2x + y = 8
y = 2x + 8
now sub in 2x + 8 for y in the other equation
3x + 2y = 2
3x + 2(2x + 8) = 2...distribute the 2 thru the parenthesis
3x + 4x + 16 = 2
7x = 2 - 16
7x = - 14
x = -14/7
x = -2
now sub -2 in for x in either equation to find y
-2x + y = 8
-2(-2) + y = 8
4 + y = 8
y = 8 - 4
y = 4
solution is : (-2,4)
Because its a square it makes every side the same length, so you would need to multiply 8 times 8.
8 x 8 = 64
Length x Height
