Answer:
The only question is whats your number add me on ig Krazy2Bray
Step-by-step explanation:
Check the picture below.
make sure your calculator is in Degree mode.
3*x=3x
3*-5=15
you just distribute the 3 to both values in the parenthesis.
so then we have
17=3x-15+8
simplify
17=3x-23
add 23 to both sides
40=3x
divide both sides by 3
x=13 1/3

For the statement to be true, 'a' and 'b' must be equal
*First expand the binomial using FOIL, then set it equal to whats given "2abi".
Then you can find the relationship between a and b.
4x + 9 = 68
Subtract 9 from both sides:
4x = 59
Divide both sides by 4
X = 59/4
X = 14.75
