Answer:
the angle is equal to 60 degrees
Answer:
X^2+3x
Step-by-step explanation:
in order to get these roots, we would set up the equation to be (x)(x+3). We can then multiply it to get x^2+3x
M=Marissa's age
k=Kendra's age
k+2=m
m+2k=35
(k+2) + 2k=35
3k+2=35
3k=33
k=11
m=k+2
m=11+2
m=13
Answer:
B
Step-by-step explanation:
12x² - 157x - 40
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 12 × - 40 = - 480 and sum = - 157
The factors are + 3 and - 160
Use these factors to split the x- term
12x² + 3x - 160x - 40 ( factor the first/second and third/fourth terms
= 3x(4x + 1) - 40(4x + 1) ← factor out (4x + 1) from each term
= (4x + 1)(3x - 40) ← in factored form → B
