Answer: y = 1x^2 - 12x + 15
Step-by-step explanation:
10 + f = 10
-10 -10
f = 10 - 10
f = 0.
Answer: <DEF & <JKL
Step-by-step explanation:
they equal 90 degrees
complementary angles equal 90 degrees
F(x) = x² + x - 20 = x² + 5x - 4x - 20 = x(x + 5) - 4(x + 5) = (x + 5)(x - 4)
f(x) = 0 ⇔ (x + 5)(x - 4) = 0 ⇔ x + 5 = 0 or x - 4 = 0 ⇒ x = -5 or x = 4
Answer: C. x = -5 and x = 4.
Answer:
64
Step-by-step explanation:
total of a triangle adds up to 180 degrees
so:
76+37=116
180-116=64
