Answer:
a) DE ≅ GF
Step-by-step explanation:
In the picture attached, the diagram is shown.
An isosceles trapezoid is a trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal. In this case, the left and right side lengths are DE and GF, respectively; then they are congruent.
Answer:
72 in
Step-by-step explanation:
Just multiply all the variable together!!!!
Answer:
75
Step-by-step explanation:
Think of this situation as a system of equations.
let y be the price of hotdogs
let x be the price of hamburgers
5y + 2x = 8
2y + 5x = 9.50
now use your solution method of choice
substitution, elimination, matrices, etc
Perimeter: P=24 ft
Lenght: L
Width: W
The length is 2 ft longer than the width:
(1) L= W+2 ft
Perimeter: P=2(W+L)
P=24 ft
2(W+L)=24 ft
Dividing both sides of the equation by 2:
2(W+L)/2 =(24 ft)/2
(2) W+L=12 ft
We have a system of 2 equations and 2 unkowns:
(1) L=W+2
(2) W+L=12
Using the method of substitution: Replacing L by W+2 in the second equation:
(2) W+L=12
W+(W+2)=12
W+W+2=12
2W+2=12
Solving foe W
2W+2-2=12-2
2W=10
Dividing both sides of the equation by 2:
2W/2=10/2
W=5
Replacing W by 5 in the first equation:
(1) L=W+2
L=5+2
L=7
Answers:
What is the width? 5 ft
What is the length? 7 ft
