This looks like: 
To solve this problem, you'll want to use the AC method to factor x^2+7x-30.
After factoring your expression will look like this:

Cancel out the x+10 because they are common factors, so you are just left with the simple x-3.
Answer is:
x - 3
all the answers would be irrational.
Since there are three kids, 3x3=9. 80-9=71. Danny and Mark and Evans ages combined is 71 years
Answer:
Step-by-step explanation:
Area of circle = 56 cm²
πr² = 56
3.14r² = 56
r²=56/3.14
r²= 17.83
r = √17.83
r = 4.22 cm
The diameter of the circle = diagonal of the square
Diagonal of the square = 2 * 4.22 = 8.44 cm
x² + x² = 8.44²
2x² = 71.2336
x² = 71.2336/2
x² = 35.6168
x = 5.967 cm
Answer:
