Answer:

x = 33

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180 for x

x = 180 - (90 + 57) = 180 - 147 = 33

If $(2x+5)(x-3)=14$, find the sum of the possible values of $x$.

MA_775_DIABLO [31]

Answer:

x = 1/4 ± 1/4√233

Step-by-step explanation:

(2x + 5)(x - 3) = 14

~Use FOIL on the left side

2x² - 6x + 5x - 15 = 14

~Combine like terms

2x² - x - 15 = 14

~Subtract 14 to both sides

2x² - x - 29 = 0

~Use the quadratic formula and simplify

x = 1/4 ± 1/4√233

Best of Luck!

Y = 2x + 3 find f(0)

vichka [17]

If $y=2x+1$ then that means $f(x)=2x+3$ and when you plug in $x=0$ you get $f(0)=2\cdot0+3=\boxed{3}$ .

Hope this helps :)
