Answer:
Step-by-step explanation:
10 - 4m + 7m = m - 10
Simply both sides:
10 + -4m + 7m = m + -10
Combine like terms:
( -4m + 7m) + (10) = m - 10
3m + 10 = m -10
3m + 10 = m - 10
Subtarct m from both sides:
3m + 10 - m = m - 10 - m
2m + 10 = -10
Subtract 10 from both sides:
2m + 10 - 10 = -10 - 10
2m = -20
Divide both sides by the 2:
2m/2 = -20/2
m = -10
<u>Answer =====> m = -10</u>

Answer:
Yes
Step-by-step explanation:
They are proportional by a scale of 1.5
The length is 15 inches and width is 9 inches
Step-by-step explanation:
Let
l be the length
and
w be the width
w = l-6
The area of rectangle is 135 ft^2
The formula for area is:
As the length cannot be negative, so we will use the value of length 15
If length 15,
w=l-6
w=15-6
w=9
So,
The length is 15 inches and width is 9 inches

All triangles equal 180 degrees.
Move everything to one side and factorize by grouping.
x⁴ - 4 = x³ + 2x
x⁴ - x³ - 2x - 4 = 0
(x⁴ - 4) - (x³ + 2x) = 0
(x² - 2) (x² + 2) - x (x² + 2) = 0
(x² - x - 2) (x² + 2) = 0
(x - 2) (x + 1) (x² + 2) = 0
Then
x - 2 = 0 or x + 1 = 0 or x² + 2 = 0
x = 2 or x = -1 or x² = -2
If x is real, then the third case has no solution. Then x = 2 or x = -1. Otherwise, we can solve over the complexes and include x = ± √2 i where i = √(-1).
