Answer:
a = 1/2 (b) (h)
Step-by-step explanation:
Use Pythagorean theorem for sub triangle on the left: 8^2 + h^2 = 22^2
Use Pythagorean again for sub triangle on the right: x^2 + h^2= 31^2
Find your base: 8+x=b
Find entire area: a = 1/2 (b) (h)
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
Plug 8 into one of the equations and you will find how many chairs total there are.
9(8) + 3 = 75
There are 75 chairs total
Answer:
9
Step-by-step explanation:
f(-6) means you plug -6 into x.
f(x)= −2/3x + 5
f(-6)= −2/3(-6) + 5
f(-6)= 4 + 5
f(-6)= 9
Answer:
The answer is -0.7
Step-by-step explanation:
is the right answer
Yes, Luis is correct.
If s is equal to the the side length, then in the problem, s is equal to 8 millimeters. 8 x 3 is equal to 24, which would equate to 24 cubic millimeters.
