Answer:
8b + 7
Step-by-step explanation:
Add like terms.
7b + b (same as 1b) = 8b
4 + 3 = 7

Answer:
12 is the answer.
Step-by-step explanation:
The best way to get the roots of the equation is to factorize the equation but when the factors are not possible then we should apply the quadratic equations formula to get the value of x.
Now we will try to factorize
x² - 8x -48 = 0
Now we multiply coefficient of highest degree term and constant term
48×1 = 48 which may be factored in 12×4. 8×6, 24×2.
Now we will choose 12×4 out of three because the 12-4 = 8 which is the coefficient of x.
Now its simple.
x²-12x + 4x -48 = 0
x(x -12) + 4(x-12) = 0
(x +4)(x-12) = 0
Therefore roots are x + 4 = 0
x = -4
and x - 12 = 0
x = 12
So the answer is 12.
Answer:
8 ft up or 32 ft down depends if she goes above sea level or down sea level
Step-by-step explanation:
if you take the 2 away and subtract 10 from 20 you get 10 then subtract the remaining two
If she whent down you would add 12 + 20
