Answer:
Step-by-step explanation:
<u>Given</u>
- DE = 3x + 2, EF = x + 5, DF = 23
<u>As per segment addition postulate</u>
<u>Substituting values:</u>
- 3x + 2 + x + 5 = 23
- 4x + 7 = 23
- 4x = 16
- x = 4
Answer:
OB. FUX) =(x+6)*x+6) that is the answer
Area= L x W and if the L is 5 yds more than the width is the equation with be...
Area(104)=Wx(W+5)
so 104=W^2+5w
w^2+5W-104 using the quadratic formula you end up getting
W=8
L=8+5=13
13*8=104
Answer:
Yes, Rain is correct
238.5 square inches
Step-by-step explanation:
Surface Area of a Triangular Pyramid,A = 1/2(a × b) + 3(1/2 × b × s)
= (1/2 × 10 × 8.7) + 3(1/2 × 10 × 13)
= 43.5 + 3(65)
= 43.5 + 195
= 238.5 square inches
The surface area of the triangular pyramid = 238.5 square inches
We are given
total number of cars =12
cost of each car = $178
now, we have to find total cost
so, we can use formula
total cost = (total number of cars)* ( cost of each car)
so, we can plug values
and we get


So, the cost of 12 cars is $2136.........Answer
