Answer:
x^2 + 3x -1
Step-by-step explanation:
f(x) = 3x-2
g(x) = x^2+1
(f+g)(x) = 3x-2+x^2+1
Combine like terms
= x^2 + 3x -1
Well since 1 tone is 2,000 pounds so you will do 7 times 2,000 which equals
14,000 pounds.
Answer:
No solution
Step-by-step explanation:
x + 2/3 = 2/3 + x - 1/4
x = x - 1/4
0 ≠ -1/4
Answer:
412.15 ft to the nearest hundredth
Step-by-step explanation:
You have to use the tangent function since you are given one leg of a right triangle and you are looking for the other leg
Let x = the distance from boat to lighthouse
So, tan 27 = 210/x
x tan 27 = 210
x = 210/tan 27
x = 412.14820 = 412.15 ft to the nearest hundredth
Answer:
x = 70°
Step-by-step explanation:
The given triangle has 2 equal sides and is therefore isosceles.
The base angles are equal, both 55°
To find x subtract the sum of the 2 angles from 180
x = 180° - (55 + 55)° = 180° - 110° = 70°
