Answer:-6y+12
Step-by-step explanation:
(2y+3)×(y-6)=2y^2-9y-18
2y^2-9y-18-2y^2+3y+30
Combine like terms
2y^2-2y^2=0
-9y+3y=-6y
-18+30=12
-6y+12
Step-by-step explanation:
first you can 1.9 7 times then you do it again but to the 10 power
Step-by-step explanation:
f(g(x))= 5(g(x))- 7 = 5(x+3) - 7 = 5x +8
g(f(x)) = f(x) +3 = 5x -7 +3= 5x -4
The sin of any given angle is:
sin(∅) = perpendicular / hypotenuse
The perpendicular of angle A will be equivalent to the base of angle B. Therefore,
Cos(B) = 243/312
B = Cos⁻¹(243/312)
B = 38.8°
The measure of angle B is 38.8 degrees.
