Answer:
8
Step-by-step explanation:
1. multiply 5 and 12 to get 60
2. multiply 5 and m to get 5m
3. the equation would be 60 + 5m = 100
4. next, subtract 60 on both sides
5. your equation so far is 5m = 40
6. then divide 5 on both sides
7. then you have your answer m = 8
Answer:
143 degrees
Step-by-step explanation:
Triangle EDF is a right triangle and we know that angle 1 is equal to 53 degrees. So, angle 2 is equal to 180-90-53 = 37 degrees. Now that we want to find angle 3, we subtract the measure of angle 2 (which is 37) from 180. That gives us 143 degrees.
Answer:
6
Step-by-step explanation:
Suppose the width is "a". Then the length is 2a.
2(a²) =72 Divide both sides by 2
a²= 36
a=6

Step-by-step explanation:
A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0
B) Since the discriminant is 0, this means the equation only has one root.
C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)
