Answer:
m=6
Step-by-step explanation:
For this figure to be a parallelogram, the sides must be the same length
4m+2 = 3m+8
Subtract 3m from each side
4m+2-3m = 3m+8-3m
m+2 =8
Subtract 2 from each side
m+2-2 =8-2
m=6
Answer: cd(x) = 4x³ — 2x² + 8x — 4
Step-by-step explanation:
c(x) = 4x - 2
d(x) = x² + 2
Therefore, cd(x) = c(x) × d(x)
cd(x) = (4x - 2)(x² + 2)
= (4x × x²) + (4x × 2) + (-2 × x²) + (-2 × 2)
= 4x³ + 8x -2x² - 4
cd(x) = 4x³ — 2x² + 8x — 4

1. The correct statement is the first one, which is: <span>Add the two equations, solve for y, and then substitute –1 for y to find x.
</span>
2. Therefore, you have the following system of equations:
<span>
4x+8y=20
-4x+2y= -30
3. When you a</span>dd the two equations, and clear the variable "y", you obtain:
10y=-10
y=-1
4. Now, you must substitute -1 for y (y=-1) to find x, as below:
4x+8y=20
4x+8(-1)=20
4x-8=20
4x=20+8
4x=28
x=28/4
x=7
Answer:
6.28 m
Step-by-step explanation:
If a wheel travels with one full revolution, it would have travelled the circumference's distance from it's starting point.
The circumference of a circle is 
Let's assume
is 3.14 and solve for the equation.
