Answer:
4x + 2(x – 3) = 4x + 2x – 11
4x + 2x - 6 = 4x + 2x - 11
6x - 6 = 6x - 11
-6 = -11
There is no solution because -6 does NOT equal -11
Answer:
0 solution
Step-by-step explanation:
4x + 2(x – 3) = 4x + 2x – 11
Solve the parentheses:
4x + 2x - 5 = 4x + 2x - 11
Subtract 2x from both sides:
4x - 5 = 4x - 11
From what you can already see that those two expressions does not equal to each other. Let’s continue solving to confirm:
(Subtract 4x on both sides)
-5 = -11
There are 0 solutions

Find the circumference and the area of a circle with radius 3 m
Use the value 3.14 for π, and do not round your answers. Be sure to include the correct units in your answers.
Answer:
The area: 28.26m^2, the circumference: 18.85m
Step-by-step explanation:
The area of a circle is 3.14(3)^2, which is 28.26, the circumference is 2(3.14)(3)=18.85m.
Answer:
Area of a circle= π[tex]r^{2}[/tex]
3.14 x [tex]3^{2}[/tex] = 18.84
The area of the circle is 18.84 [tex]m^{2}[/tex]
Circumference of a circle = 2πr
2 x 3.14 x 3 = 18.84
The circumference of the circle is 18.84 m
They are both the same number but the area is squared.

Explain how the percent equation relates proportional quantities
the percent equation being
PART = PERCENT * WHOLE
Answer: This is the best I could find for you
Step-by-step explanation:
"When the ratio of part to whole is equal to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion."
