Answer:
no because for right angle triangle the sum of the sq of the two smallest side is equal to the sq of biggest side
Answer: 2(h × W) + 2(h × L) + 2(W × L)
Step-by-step explanation: The width, height, and length of a box can all be different. If they are the same, then the box will become a perfectly square box. The volume, or amount of space inside a box is h × W × L. The outside surface area of a box is 2(h × W) + 2(h × L) + 2(W × L)
remember, you can do anything to an equation as long as you do it to both sides
we can do a subsitution
y=x+6
y=-7x-10
since y=x+6, we can subsitute x+6 for y in the other equation
y=-7x-10
x+6=-7x-10
add 7x to both sides
8x+6=-10
minus 6 from both sides
8x=-16
divide both sides by 8
x=-16/8=-2
the valu eof x that satisfies both equations is x=-2
Answer:
Let x be the number.
Given the statement: Three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen.
" sum of a number and four" translated to x + 4
"Three sets of a sum of a number and four" translated to 3(x+4)
"sum of seven times the same number and thirteen" translated to 7x + 13
then;
the expression for the given statement become;

Using distributive property: 

Combine like terms;

Therefore, the simplified expression for Three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen. is,
