<span>Based on Pythagoras’s Theorem:
x^2 + (x+2)^2 = 10^2
2x^2 + 4x + 4 = 100
X^2 + 2x -48 = 0
(x + 8)(x - 6) = 0
Solving for x = 6, the sides are 6m and 8m.</span>
A term is a single constant or variables that have non-zero coefficients.
Since there are 4 terms with non-zero coefficients in the following expression, there are 4 terms.
Hope this helps.

Step-by-step explanation:
Answer:
Volume: 2000 cm^3 Surface Area: 1360cm^2
Step-by-step explanation:
Ok, so we know the formula for volume is length x width x height, so we can substitute in the numbers given, so we end up with:
25 x 4 x 20
when we multiply them together, we get:
2000cm^3. That's the volume.
The formula for Surface Area is:
S.A.=2(lw+wh+lh) . Now we substitute in the numbers given
S.A.=2( (25 x 4)+(4 x 20)+(25 x 20)) . Then we add and multiply, so we get:
S.A. = 1360cm^2
The Surface Area is 1360cm^2.
Hope this helped, sorry if I was wrong somewhere!
