Answer:
<h2>a. 2,025 ft</h2><h2>b. 8,100 is a perfect square. </h2>
Step-by-step & explanation:
<em>It is a perfect square because if it wasn't, it wouldn't be equally a whole number when divided by 4 or 2,025 exactly on ALL 4 sides and when finding the root of 8,100 it's a perfect 90. As you should already know a perfect square has a given 90 degree angle.</em>
Tarp = 8,100 sq ft.
- anchored corners at the base.
- Square infield.
Well if there's 4 bases, divide 8,100 by 4.
8,100 / 4 = 2,025
One base to another base is 2,025 ft.
Answer:
e = 7
Step-by-step explanation:
Eliminate parentheses using the distributive property.
18e -48 = 5e +43
13e -48 = 43 . . . . . . . . subtract 5e from both sides
13e = 91 . . . . . . . . . . . . add 48 to both sides
e = 7 . . . . . . . . . . . . . . divide both sides by 13

<em>Comment on equation solving</em>
If there are parentheses or fractions, it usually works well to eliminate those. The distributive property is used to eliminate parentheses. Fractions can be eliminated by multiplying the equation by the denominator. (We mean 'multiply both sides of the equation by the denominator'.) If you have excellent skill with arithmetic using fractions, you don't need to go to the trouble to eliminate them.
After the numbers in the equation are mainly integers or decimals, the next step is to look to see where the variable of interest is located. You want to do what it necessary to put all of the variable terms on one side of the equal sign, and everything else on the other side. The procedure generally is to decide what you don't want, and subtract that from both sides of the equation.
Finally, you divide by the coefficient of the variable, so the variable stands alone on one side of the equal sign. This shows you the solution.
Answer:
Step-by-step explanation:
Part A:
(400-325)/(5-0)
75/5= 15 is the slope
Part B:
(0, 325) (5, 400)
y - 325 = 15(x - 0)
Part C:
y = 15x + 325
Part D:
x = 12
y = 15(12)+ 325
y = 180 + 325
y = $505
we just need make inside square 0
x+10=0
x=-10
y-8=0
y=8
so the center is (-10,8)
Answer:
-38
Step-by-step explanation:
You replace the x with 5.
turns it into -3 (5)^2+9(5)-8
-3(25)+45-8
-75+45=-30-8=-38
