Answer: x = -4
Please mark as brainlist.
Answer:
The equation is
Let n represent the number
4n + (-2) = 5n + 8
4n - 2 = 5n + 8
Solve for n
Group like terms
4n - 5n = 8 + 2
-1n = 10
n = 10/-1
n = -10
The number is -10
C because you have to multiply the four measures together.
Use system of equations. We know l=w+90 and 2w+2l=700. Substitute w+90 in for l and solve.
l=220
w=130
Answer:
Step-by-step explanation:
its an obtuse angle so add up a and c then subtract that by 180 and you get 120
