Square root both sides. The unreduced answer is root 28. Now. To reduce root 28, you need to break it down into factors and hope one of them is a perfect square.

4*7=28, and 4 is a square number. The square root of 4 is either positive or negative 2. Now that you've found that square, pull it out from under the square root symbol. Under the root symbol, you're left with 7 (not a perfect square).

Therefore, your answer is C

Kevin plans to put concrete on a rectangular portion of his driveway the portion is 10 feet long and 3 inches high the price of

Fudgin [204]

First we need to know the total volume of concrete used:
$V_total = \frac{cost_{total}}{cost{unit}}$
$V_total = \frac{\$72.98}{\frac{\$90}{yd^{3}}}$
$V_total = 0.7407yd^{3}$

Now we can use the formula for volume of a rectangular prism:
$V=lwh$
Convert everythig to yards and substitute:
$0.7407yd^{3}=(3.33yd)(w)(0.08333yd)$
$w=\frac{0.7407}{3.33 \times 0.08333}$
$w \aprox 2.66yd$

HURRY PLEASE <br><br> What is the solution of the system 4x+3y=6 2x+2y=5

jolli1 [7]

The first given equation is:
4x + 3y = 6
which can be rewritten as:
2(2x) + 3y = 6 .............> equation I

The second given equation is:
2x + 2y = 5
which can be rewritten as:
2x = 5 - 2y ........> equation II

Substitute with equation II in equation I to get the value of y as follows:
2(5-2y) + 3y = 6
10 - 4y + 3y = 6
-y = 6-10 = -4
y = 4

Substitute with the y in equation II to get x as follows:
2x = 5 - 2y
2x = 5 - 2(4)
2x = 5 - 8 = -3
x = -3/2

From the above calculations:
x = -3/2
y = 4
