Answer:
27 in^2
Step-by-step explanation:
3 x 3 = 9
2 x 9 = 18
18 + 9 = 27
52 + 75 will give you 127. Then you divide by 2 which gives you the answer of 63.5
Formula for triangle perimeter is: a + b + c. In this scenario we have:
a = 3 feet 8 inches
b = 2 feet 10 inches
c = 4 feet
a + b + c =
= 3 ft + 8 in + 2 ft + 10 in + 4 ft =
= 9 ft + 18 in
We know that 1 foot is 12 inches, so we can simplify the result to this form:
10 ft + 6 in
or:
<u>10.5 feet</u>
X = y x z
10 = (-4) x z
Z= -10/4 = -5/2
So now we know z = -5/2
we can find y when x = 2
Again x = y x z
<span>
2 = y x
(-5/2)</span>
<span>So y =2 x (
-2/5) = - 4/5</span>
Double check:
x = yx (x = 2 , y = -4/5), z = -5/2)
<span>
2 = (-4/5) x (-5/2) = 20/10 = 2
Answer: when x = 2, y = -4/5</span>
