9(2j+7+5j) Foil this out to get 18j+7+45j then 63j+7
Answer: 18j+7+45j , 63j+7 I think
If y = 2, to find the value of y + 6, we need to substitute the value of y (2) into the expression y + 6. Substituting 2 for y, we get the equation 2 + 6. Since 2 + 6 = 8, that means that substituting y = 2 into the expression y + 6, we get 8.
Answer:
x = 26°
Step-by-step explanation:
The measure of the secant- secant angle x is one- half the difference of the measures of the intercepted arcs , larger subtract smaller
x = 
(66° - 14°) = 0.5 × 52° = 26°
Answer: Raina's distance from the mountains is 176 miles
Step-by-step explanation:
Let x represent her average rate on the trip to the mountains.
If her average rate was 22 miles per hour faster on the trip home, it means that her average rate on the trip home is (x + 22) mph
Distance = speed × time
There was heavy traffic on the way there, and the trip took 6 hours. This means that the distance on her way to the mountain is 6x
When Raina drove home, there was no traffic and the trip only took 4 hours. This means that the distance on her way to home is
4(x + 22)
Since the distance covered is the same, then
6x = 4(x + 22) = 4x + 88
6x - 4x = 88
2x = 88
x = 88/2
x = 44
Raina's distance from the mountains is
6 × 44 = 176 miles
