Answer:
5. x = -3
6. x = -2
7. x = 1/2
8. x = 9/5
Step-by-step explanation:
Answer:
what is the question about the given numbers
2x + 1 = 9
First step is to remove the integer (whole number)
Remove 1
2x = 8
Then divide by 2 to find x
x = 4
P = 58 inches
58 = 2 x height + 2 x width
58 = 2h + 2w
58 = 2 x 18 + 2w
58 = 36 + 2w
Get rid of the whole numbers
22 = 2w
Divide b 2 to find w
w = 11
This is a special 60-30-90 triangle, and the angle measure of x is
Answer: 45.24
Explanation:
(Use the formula “1/2 a b sinC”)
Area = 1/2 x 9 x 15 x sin(51) ≈ 45.24 square units
