Answer:
9x^2 + 9x -70
Step-by-step explanation:
Use the distributive property to solve
(3x-7) (3x+10)
multiply 3x x 3x = 9x^2
multiply 3x(-7) and 3x(10)
add -21x + 30x = 9x
multiply -7 x 10 = -70
Assuming that C is the hypotenuse...
The formula you want to use is:
a^2 + b^2 = c^2
We start by squaring 10, which is 100. 5^2 is 25. Now that we have the values, we can do the equation.
100+25=c^2 100+25=
Now, square root 
C= 11.180
Answer:
I believe it's this:
A. M= (C-12)/a (Not sure.)
Step-by-step explanation:
T=5
4=2+2/5t
Subtract 2 from both sides.
2=2/5t
Multiply both sides by 5/2.
t=5
Answer:
Step-by-step explanation:
Starting at 5 on the number line, 5 + (-3) is 3 units to the left of 5; that is, you are at 2 on the number line.
