Answer:
<h3>length = 28 cm</h3><h3>width = 12 cm</h3>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 80cm
The length is 4 inches longer than twice the width is written as
l = 4 + 2w
Substitute this into the formula and solve for the width
That's
80 = 2( 4 + 2w) + 2w
80 = 8 + 4w + 2w
6w = 80 - 8
6w = 72
Divide both sides by 6
w = 12 cm
Substitute w = 12 cm into l = 4 + 2w
That's
l = 4 + 2(12)
l = 4 + 24
l = 28cm
Therefore
length = 28 cm
width = 12 cm
Hope this helps you
<span>First we add 2m to both sides, leaving 7m + 72 = 52 (since -2m + 2m cancels out). Next, we subtract 72 from both sides, bringing us to 7m = -20. Solving for m, we get -20/7. Since this is not one of the listed options, it is possible that the original poster has made a typographical error.</span>
Answer:
<h2>A) 5</h2>
Step-by-step explanation:
The equation of a circle:
(h, k) - center
r - radius
We have the equation:
<em>divide both sides by 3</em>
The square route is what times itself can get you that number such as 64, 8*8= 64, 8 is the square route.
Answer:
x = 55
y = 70
Step-by-step explanation:
Since all three sides are equal, as indicated by the lines on the sides, all three angles are equal
Since a triangle is equal to 180 degrees
180/3 = 60
Each angle is 60 degrees
x+5 = 60
Subtract 5 from each side
x +5-5 = 60-5
x = 55
y-10= 60
y-10+10 = 60+10
y= 70
