Answer:
x = 4
Step-by-step explanation:
6x - 8 = 4x
<em>subtract 4x from both sides of the equation</em>
6x - 4x -8 = 4x - 4x
2x - 8 = 0
<em>add 8 to both sides of the equation</em>
2x - 8 + 8 = 0 + 8
2x = 8
<em>divide both sides of the equation by 2</em>
2x/2 = 8/2
x = 4
Answer:
8)61.5 9)42.1
Step-by-step explanation:
8)61.5
area of square 10×10=100
circle=pie r^2
3.5^2×pie
=38.5
100-38.5=61.5
9)14×14=196
14/2=7
7=radius
pie×7^2
=153.9/2(because circle is half)
=76.95
76.95×2
=153.9
=196-153.9
42.1

Answer: 2x³(x² + 5x - 11)
<u>Step-by-step explanation:</u>
2x⁵ + 10x⁴ - 22x³
Factor out the GCF (2x³)
2x³(x² + 5x - 11)
Since there are no values whose product is -11 and sum is +5, this cannot be factored further.
Answer:
125
Step-by-step explanation:
divide both sides of the equation by 0.8
0.8÷0.8=0.8÷100
any expression divided by 1 is itself
x=100÷0.8
divide the numbers
100÷0.8=125
125 is your answer
