What triangle? There is no picture
X intercept is when y = 0
y = 3x + 12
0 = 3x + 12
3x + 12 = 0
3x = 0 - 12
3x = -12
x = -12/3
x = -4
x intercept is = -4.
Answer:
a^2
−10a+21
Step-by-step explanation:
(a−7)(a−3)
Apply the distributive property by multiplying each term of a−7 by each term of a−3.
a^2
−3a−7a+21
Combine −3a and −7a to get −10a.
a^2
−10a+21
