Answer:
x^2+6x+8
Step-by-step explanation:
(x+4)(x+2)
FOIL
first: x*x = x^2
outer: x*2 =2x
inner : 4*x =4x
last: : 2*4 =8
Add them together
x^2 +2x+4x+8
Combine like terms
x^2+6x+8
X=25cos10+30cos100
y=25sin10+30sin100
v=√(x^2+y^2)
α=tan(y/x)
Rounding to two decimal places in intermediate steps...
x≈19.41, y≈33.89
v≈39.05
α=60.20°
So (39.05, 60.20°)
