Answer:
Step-by-step explanation:
We have the sides for both the rectangle and the square. The problem says that the area of the rectangle is 16 more than the area of the square. The area of the rectangle is
(x + 16)(x)
The area of the square is
(3x - 2)(3x - 2)
"The area of the rectangle" "is" "16 more than the area of the square"
x(x + 16) = (3x - 2)(3x - 2) + 16
FOILing the left side and then setting it equal to the FOILing of the right side:
and
Now we will get everything on the same side of the equals sign, set the polynomial equal to 0, and factor to solve for x:
Factor that however you learned best to factor quadratics (the quadratic formula works for a second degree polynomial every time!) to get that
x = 1 or x = 2.5

Answer:
22-18-25,
19-24-30,
7-24-25
Step-by-step explanation:
In a triangle with side lengths , , and , any two sides must have a sum larger than the third.
Using this rule, the possible side lengths out of these choices that could form a triangle are:
22-18-25,
19-24-30,
7-24-25
4/2 it goes over 4 and up 2
Answer:
63462 pies
Step-by-step explanation:
De la pregunta anterior, debemos encontrar el área del sector
La fórmula se da como:
θ / 360 × πr²
Dónde:
θ = 45 °
radio = 402 pies
Área del sector =
45/360 × π × 402²
= 63461.742399 pies
Aproximadamente el área de la ocupada por el parque = 63462 pies
