Step-by-step explanation:
what is that X, and X²???
If its volume (Not so sure about surface area?) than its 432 inches^3
Prime for 2 digit odd number: 13 , 11 , 17, etc
Odd number that is composite: 39, 25, 15, etc
Hope this helps
Let Gavin be G
Let Seiji be S
G + S = 425
G = 25 + S
I can't really graph, but plug in some numbers to G and S that works in BOTH equations. Then graph it.
G + S = 425
G = 25 + S
(25 + S) + S = 425
2S + 25 = 425
2S + 25 (-25) = 425 (-25)
2S = 400
2S/2 = 400/2
S = 200
Seiji made 200 dollars
Now choose one of the equations to use (the easier the better) in this case i will choose this one:
G = 25 + S
pug in 200 into S (because that is how much Seiji made)
G = 25 + (200)
G = 225
Seiji made 200, Gavin made 225
200 + 225 = 425, which is the total amount the made

Answer:
28
Step-by-step explanation:
We know that the heights and bases of all of the parallelograms will be the same because they are equal, therefore, since the height of 2 parallelograms is 14, the height of one parallelogram is 14 / 2 = 7. Since the areas of all of the parallelograms are congruent, the area of one parallelogram is 308 / 4 = 77. The parallelogram area formula is A = bh where A, b and h are area, base and height respectively and we know both the area and height so we need to solve for b. Doing so we get 77 = b * 7 so that means b = 11. The length of y is two bases + 6 and since we know the base is 11, y = 11 * 2 + 6 = 22 + 6 = 28.
