A large truck is going down a hill at 60 miles per hour. The driver needs to begin slowing down by shifting the gears. The speed

goes down by 10 miles per hour each time he downshifts. Which expression shows his speed after three shifts?

It would be D. 69 + ( - 10 x 3 ). Because here are the keywords. He was going DOWN (negative) at a hill. And he now needs to SLOW DOWN (negative) by shifting the gears. Then he speeds DOWN (negative) 10 miles PER hour. And it says, how much speed after 3 shifts.

the length of a rectangular garden is 3 m greater than the width. The area of the garden is 70m squared. find the dimensions of
Lerok [7]
A = l x w

so you know that the length is 3m longer than the width, so you could use a formula to represent that

w = l + 3

you then substitute the second equation into the first to solve for l

70 = l x (l +3)
70 = l^2 + 3l

you could then rearrange the formula and solve for l using the quadratic formula 

0 = l^2 + 3l - 70

l = -3 +- (square root (3)^2 - 4(1)(70)) / 2(1)
l = -3 +- (square root 9 + 280) / 2
l = -3 +- (square root 289) / 2
l = -3 +- 17 / 2

then you solve for the two seperate roots

l = -3 + 17 /2
l = 14 / 2
l = 7

or 

l = -3 - 17 / 2
l = -20 / 2
l = -10

since a length cannot be negative, this root is not viable. therefore l = 7

to solve for w you would use

w = l + 3
w = 7 + 3
w = 10 

hope this helps! if you did not understand a step or concept please let me know!
