2(5x+7)+8x-7=27
We move all terms to the left:
2(5x+7)+8x-7-(27)=0
We add all the numbers together, and all the variables
8x+2(5x+7)-34=0
We multiply parentheses
8x+10x+14-34=0
We add all the numbers together, and all the variables
18x-20=0
We move all terms containing x to the left, all other terms to the right
18x=20
x=20/18
x=1+1/9
The missing factor is (7s+5) since 7s * s is 7s^2 and 5*2= 10

Answer:
7^5 = 16,807
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
__
Here, we have a=7, b=2, c=3, so ...
(7^2)(7^3) = 7^(2+3) = 7^5 = 16,807
Answer:
P is complementary to x
Step-by-step explanation:
Complementary means adding to 90 degrees
P+x = 90 degrees
So P is complementary to x
