Define x :
--------------------------------------------
Let the shorter leg = x
Longer leg = x + 7
Hypotenuse = x + 7 + 7 = x + 14
--------------------------------------------
Solve x :
--------------------------------------------
a² + b² = c²
x² + (x+7)² = (x+14)²
x² + x² + 14x + 49 = x² + 28x + 196
2x² + 14x + 49 = x² + 28x + 196
x² - 14x - 147 = 0
<span>(x - 21)(x + 7) = 0
</span>x = 21 or x = - 7 (rejected, because length cannot be negative)
--------------------------------------------
Find the legs and hypotenuse:
--------------------------------------------
shorter leg = x = 21
longer leg = x + 7 = 21 + 7 = 28
hypotenuse = x + 14 = 21 + 14 = 35

Answer: The side length of the triangles are 21m, 28, and 35m.

Answer:
It would probably be 36t
Step-by-step explanation:
because if you think about It.
It is mainly asking you how long it is going to take, so you need a a equation to find the answer.
-John needs 36 copies
- Hp printers out 16 in 5 minutes
- Epson printer out 4 in 1 minutes
so 36 x t or 36t
Answer:
Step-by-step explanation:
About 12% of the land is arable and less than 6% currently is cultivated. Normally, Afghanistan grew about 95% of its needs in wheat and rye, and more than met its needs in rice, potatoes, pulses, nuts, and seeds; it depended on imports only for some wheat, sugar, and edible fats and oils. Fruit, both fresh and preserved (with bread), is a staple food for many Afghans. Agricultural production, however, is a fraction of its potential. Agricultural production is constrained by an almost total dependence on erratic winter snows and spring rains for water; irrigation is primitive. Relatively.
