Veinte y quatro veinte y quatro
The ratio of the areas is the ratio of the squares of the sides ( which is 10:15 or 2:3) so the answer is
2^2 : 3^2 = 4:9.
The ratio of the perimeters = ratio of corresponding side = 2:3.
A)
a+b=180 and a=2(b-30) using this in the first equation gives you:
2(b-30)+b=180
2b-60+b=180
3b-60=180
3b=240
b=80 so a=100
Andre's score was 100 and Brandon's score was 80.
b)
100x-200>50x-75 subtract 50x from both sides
50x-200>-75 add 200 to both sides
50x>125 divide both sides by 50
x>2.5
Explanation
The question requires that we figure out the sides that represent the top/bottom faces and the left/right faces.
We are given the plan of the aluminum sheet
The top, bottom, left and right faces are shown below
The dimension for the top and bottom is
Since they are two
Therefore the total area for the top and bottom will be
For the left and right faces, the dimensions are
The dimensions of the left and right faces will be
Since they are two, then
The area will be
Answer:gcf is 12 .
12(2+7)
Step-by-step explanation:write gcf first then this ( and then think what is 24 times 12 which is the GCF which is 2 and think what is 84 divide 12 which is 7.Now put 12 ( 2+7)
Hope it helps :)
