Answer:
width = 18 inches
length = 56 inches
Step-by-step explanation:
Let x = width
Let y = length
<u>Equation 1</u>
If length of the rectangle is 2 more than triple the width, then:
⇒ y = 3x + 2
<u>Equation 2</u>
Perimeter of a rectangle = 2(width + length)
If the perimeter is 148 inches, then:
⇒ 148 = 2(x + y)
<u>Solve by substitution</u>
Substitute Equation 1 into Equation 2 and <u>solve for x</u>:
⇒ 148 = 2(x + 3x + 2)
⇒ 148 = 2(4x + 2)
⇒ 148 = 2 · 4x + 2 · 2
⇒ 148 = 8x + 4
⇒ 148 - 4 = 8x + 4 - 4
⇒ 8x = 144
⇒ 8x ÷ 8 = 144 ÷ 8
⇒ x = 18
Substitute found value of x into Equation 1 and <u>solve for y</u>:
⇒ y = 3(18) + 2
⇒ y = 54 + 2
⇒ y = 56
<u>Conclusion</u>
The dimensions of the rectangle are:
- width = 18 inches
- length = 56 inches
Answer:
that would be 1
Step-by-step explanation:
in this equation x=74 and 74/74 equals one
Answer:
the y intercept is 2 in both cases
Step-by-step explanation:
the y intercept is where it crosses the y axis
y intercept =2
the function y = 3x+2 is in the form y= mx+b
where b is the y intercept
b=2 so the y intercept is 2
2=2 so the y intercepts are equal
I think this is what you have to do.
Rs+t=u
first you have to subtract t:
Rs=u-t
Now divide by R:
s= u-t/r
Hope this helped!
Answer: mmm I don’t even understand what you trying to say but this doesn’t look like a question to me, is this even a question just saying
