1.  9(3)+3 = 27+3 = 30
2. 9(8^{4}) = 9(4096) = 36864
3. 9-6+3 = 6
4. 6(5)+30 = 30+30 = 60
5. 6(8^{3}) = 6(512) = 3072
6. (8^{3})+84 = 512+84 = 596
7. 200+51 = 251
8. 3(18)+18^{2} = 54+324 = 378
9. 12(24)-36 = 288-36 = 252
10. 4(11+90)+10 = 44+280+10 = 334
11. 8-8 = 0
12.14(95)-1264+1 = 1330-1264+1 = 66+1 = 67

Plugging 10 for k in the expression gives us
2(10)^2+5(10)+1 We simplify this expression to  200+50+1=251
251 is your answer

A rectangular parking lot has a length 20 H more
leva [86]

Let the width = X

The length would be X + 20

Area = Length x width:

2400 = x * (x+20)

Simplify:

2400 = x^2 + 20x

Subtract 2400 from both sides:

x^2 + 20x - 2400 = 0

Factor:

(x-40) (x+60) = 0

Solve for both x's:

x = 40 and x = -60

The dimensions of a parking lot have to be positive values so you would use x = 40.

The width = x = 40

The length = x +20 = 40+20 = 60

The dimension of the parking lot is 40H x 60H

-1/2 because slope is the rise over the run. If you count on the grid from one point on the line to another you go up one and 2 to the left meaning the slope is 1/2, buttttt when the line decreases going to the right, it has a negative slope so you just add a - sign in front
