Answer:
Step-by-step explanation:
x²-7x+10=0
(x-2)(x-5)=0
x=2 or x=5
Angle 12 and Angle 10 are vertical angles.
7 + x/4 = 5 (common denominator is 4)
4(7+x/4) = 4 x 5 (distribute the 4 though parenthesis)
4 *7 +4x/4 = 4 x 5
4 * 7 + x = 4 x 5
28 + x = 4 x 5
28 + x = 20 (subtract the 28)
x = 20 - 28
x = -8
Answer:
x(3x+14)
Step-by-step explanation:
what do those terms share? they share the letter "x"
therefore we multiply x by 3x^2/x + 14x/x
3x^2/x = 3x and 14x/x = 14
(15 is your answer)
Divide numerator by denominator, cancel out any common factors
