Answer:
Multiply the first two binomials: (x+2) & (x+4) using the FOIL method (First, Outer, Inner & Last).
(x+2)(x+4) = x^² + 4x + 2x + 8 = x^² + 6x + 8
Then we multiply the trinomial that we got from the first stage and multiply that by the remaining binomial:
(x^² + 6x + 8) (x + 4)
= x^³ + 4x^² + 6x^² + 24x + 8x + 32
Collect the like terms together to give you:
x^³ + 10x^² + 32x + 32
If x+1,000=4 what’s your answer
Answer:
x ≈ 57.8°
Step-by-step explanation:
using the Sine rule in the triangle
= 
( cross- multiply )
8 × sinx = 11 × sin38° ( divide both sides by 8 )
sinx = 
, then
x = 
( ) ≈ 57.8° ( to 1 dec. place )
Answer:
f(7)=58
b(-2)-a(12)=-188
Step-by-step explanation:
f(7)=(7)^2+9
49+9
f(7)= 58
b(-2)-a(12)=8(-2)-14-13(12)-2
-16-14-156-2
=-188
