This can be done in two ways
One method is to check the answer options in both f(x) and g(x) and select the one that matches for both.
The second is to form a quadratic equation and solving as such:
f(x) = g(x)
-x² + 4x + 12 = x + 8
x² - 3x - 4 = 0
(x - 4)(x + 1) = 0
x = 4; x = -1
Only x = 4 is given in the options, so the answer is B
800-50=750 so 750+50=800 the dryer maybe go be 750
Answer:
w = 25
Step-by-step explanation:
- 45+30 = 100 - w
- 75 = 100 - w
- w = 100 - 75
- w = 25
Answer:
top left, S is the midpoint of RT, given
left 2nd row, US=RS is the definition of midpoint
right 2nd row, US=RS
3rd row,US is congruent to ST, definition of an isosceles triangle
4th row, triangle STU is an isosceles triangle, due to SSS
Hope this helps! :)
