Answer:
Since this is a multi-part question, just look at the bolded parts under each letter. I hope this helps a bit ;)
Step-by-step explanation:
A)
All sides of a square are congruent. "s" represents the square's perimeter:
s=4x.
"r" is the rectangle's perimeter:
r= 4x+26
since the perimeter = 2W + 2L:
2W + 2L= 4x+ 26
and W=x, so:
2x + 2L= 4x + 26
Subtract from both sides:
2L= 2x +26
Divide both sides:
the length of the rectangle "L"= x +13.
B) Plug 5 into the equations:
L= 5+ 13 or 18.
2(18) + 2(5)= r
36+ 10 = r or 46
s= s+ 26
s= 46-26 or 20.
20/4= 5...
It seems (at least to me, feel free to give constructive criticism) that the only logical conclusion is that 5 <u>could</u> be the value of x.
C) You would likely need to use substitution to solve, but unless I am much mistaken, this looks like an infinite-solutions equation.
L=w+13
Answer:
8.
Step-by-step explanation:
Dado que Laura tiene 40 láminas repetidas, si coloca 5 de estas láminas en cada página de su álbum, para determinar cuántas páginas de su álbum podrá Laura completar se debe realizar el siguiente cálculo:
40 / 5 = Cantidad de páginas
8 = Cantidad de páginas
Así, colocando 5 láminas por página, Laura podrá completar 8 páginas de su álbum.
You need to do like this:
Plug the numbers into the formula:
because they said
<u>is </u>90 and
<u>of</u> what?
Multiply diagnally: 100 × 90 = 9000 ÷ 82 ≈
109.76
i don't really sure it was completly correct but hoped it helps:)
