If the length is 7/6 the width w then the perimeter is w + (7/6)w + w + (7/6w)
= 2((7/6)w + w) = 2w + (14/6)w = (26/6)w = (13/3)w.
So the answer is the last one.
Say base1 = 26 and base2 = 12 then your height is 18.
1/2 (18) times ( 26+12)
So that's 9 times 38=342
342 squared is your answer
Answer:
A -(27x + 7)
B -(15x + 8 )
C -9(2x + 1 )
Step-by-step explanation:
-1/2 (30x + 16) = -15x-8
An equiavalent expression for 40+36 can be:
46+30
50+26
etc.
As long as the expression equals 76, it is correct
hope this helps
Step-by-step explanation:
To begin, let’s represent both numbers with letters; x for the smaller number and y for the larger one
The question states that both numbers sum up to 65. With that, we can create our first equation:
x+y = 65
You also went on to say that the smaller number multiplied by 2, is equal to the sum of the larger number and 10. Therefore
2x = y+10
We can rearrange the first equation, place it in the second equation and find our answer. So,
Rearranging equation 1, we have y=65-x. Hence:
2x = 65-x +10
3x = 75
x= 75/3 = 25
Substituting this value into equation 1, we have ‘y’ to be 40 {65–25}
Proof: 2*25 = 50 = 40+10
