Answer:
10
Step-by-step explanation:
3c - 5 =2c +5
3c - 2c =5 +5
c=10
Yes it is greater than 1/2
Answer:
x³ + 7x² - 6x - 72
Step-by-step explanation:
Given
(x + 6)(x + 4)(x - 3) ← expand the second and third factor, that is
(x + 4)(x - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 3) + 4(x - 3) ← distribute both parenthesis
= x² - 3x + 4x - 12 ← collect like terms
= x² + x - 12
Now multiply this by (x + 6) in the same way
(x + 6)(x² + x - 12)
= x(x² + x - 12) + 6(x² + x - 12) ← distribute both parenthesis
= x³ + x² - 12x + 6x² + 6x - 72 ← collect like terms
= x³ + 7x² - 6x - 72
Answer:
x=7
Step-by-step explanation:
since the ray bisects we know <CAT and <TAR are equal
so we can set up the equation like this: <CAT + <CAT = <CAR
(5x)+(5x)=(9x+7)
calculate equation and you'll get x=7
