X+60 + 70 = 180 (straight line)
x+130=180
x= 180 -130
x=50
The |...| means absolute value meaning everything inside is a positive number. The first problem is 16+12= 28. |-5|= 5
Hello. In order to solve this problem, you need to write an equation. Hence, you determine this equation:
8 + 2x = 8(x-5)
8 + 2x = 8x - 40
8 + 40 = 8x - 2x
48 = 6x
x = 8.
Answer:
B
Step-by-step explanation:
f(x) - g(x)
= 2x² - 4x - 3 - (x - 4)(x + 4) ← expand using FOIL
= 2x² - 4x - 3 - (x² - 16) ← distribute by - 1
= 2x² - 4x - 3 - x² + 16 ← collect like terms
= x² - 4x + 13 → B
