Answer:
m∡A = 50°
Step-by-step explanation:
since they are complementary they must equal 90°
4x+6 + 4x-4 = 90
8x + 2 = 90
8x = 88
x = 11
∡A = 4(11)+6 = 44+6 = 50
Answer:
1 13/30
Step-by-step explanation:
First you want to make the denominators the same. You do this by multiplying them. However, whatever you do you to the denominator, you must also do to the numerator:
-
=
-
=
Now reduce to simplest terms:
=1
Answer:
7/8
Step-by-step explanation:
0.875 = 875/1000
875/1000 Divide numerator and denominator by 125
7/8
Answer:
$6000.
Step-by-step explanation:
360/3(years)= 2% of Principle
so
120=2% of principle
2%=1/50
120*50=6000
Ans.=$6,000
The last one
You’re completing the square here so you have to find (1/2b)^2. In this case it’s 1. So you have to add 1 to both sides. Then you have to solve for it
It becomes
(x-1)^2 = -7
Then you have to find the square root
(x-1) = √-7
x-1 = √7 √-1
x-1= ± i √7
x= 1 ±i √7
That’s your answer and d is the only one that matches with it
