M in (-oo:+oo)
m+11 = (1/4)*m-(2*m) // - (1/4)*m-(2*m)
m-((1/4)*m)+2*m+11 = 0
m+(-1/4)*m+2*m+11 = 0
11/4*m+11 = 0 // - 11
11/4*m = -11 // : 11/4
m = -11/11/4
m = -4
m = -4

Answer:
45
Step-by-step explanation:
if you do:
0.50*90 it will equal 45
45+45= 90
5. c = 13
6. b=6
7. b=8
8. a=30
9. a=2√3
Step-by-step explanation:
We will use Pythagorean theorem in each to find the length of missing side.
5. a=12, b=5
Putting in formula
Taking square root on both sides
Therefore,
c = 13
6. a=8 , c=10
Putting in formula
Taking square root on both sides
b=6
7. a=15, c=17
Putting in formula
Taking square root on both sides
b=8
8. b=40, c=50
Putting in formula
Taking square root on both sides
a=30
9. b=2 , c=4
Putting in formula
Taking square root on both sides
a=2√3
