multiply first equation by -2 and add to 2nd equation
-4x-6y=4
<u>4x+7y=-6 +</u>
0x+1y=-2
y=-2
sub back
2x+3y=-2
2x+3(-2)=-2
2x-6=-2
2x=4
x=2
(x,y)
(2,-2)

AO^2 = side a^2 - BO^2
AO^2 = 41^2 -40^2
AO^2 = 1,681 -1600
AO^2 = 81
AO = 9
DO^2 = side b^2 -BO^2
DO^2 = 50^2 -40^2
DO^2 = 2,500 -1,600
DO^2 = 900
DO = 30
Diagonal AD = AO + DO = 9 + 30 = 39 inches

Answer:
Formula for the volume of a rectangular prism:
V = length x width x height
To solve, substitute the dimensions given in the problem and multiply.
Answer:
The mean is 44.2
Step-by-step explanation:
1. Add all the numbers: 29+31+35+37+38+44+43+46+46+93=442
2. Divide the sum by the amount of numbers: Since there are 10 numbers in all our equation is 442 / 10 which equals 44.2 and gives us our answer
