RUDIKE [14]2 years ago

Perimeter is the addition of all 4 sides and a square as all the same sides. so every side will be the same. so if you divide 216 by 4 you get 54. you can check this by adding 54+54+54+54=216 or 54x4=216

Factor x^2+6x-16 into the form (x+a)(x-b), what is a and b?
vfiekz [6]

Answer:

a=-8 b=2

Step-by-step explanation:

x^2+6x-16

x^2+(8-2)x-16=0

x^2+8x-2x-16=0

X(X+8)-2(X+8)=0

(X+8)(x-2)=0

Compare with (X+a)(X+b)

Where we get a=-8 b=2

Use elimination method - I am eliminaing the y-variable.

1(5x + 8y = 16)    →    5x + 8y = 16
4(6x  - 2y = 54)    →  24x - 8y = 216
         Add equations: 29x       = 232
            Divide by 29:    x        = 8

Answer: x = 8

Solve for x: 4 over x equals 5 over 10
julsineya [31]

Answer:

x = 8,

Step-by-step explanation:

\displaystyle \frac{4}{x} = \frac{5}{10}.

x \ne 0 for it is a denominator. Multiply both sides with the product of the two denominators: 10\;x:

\displaystyle \frac{4}{x}\cdot (10\; x) = \frac{5}{10}\cdot (10\;x).

40 = 5\; x.

Multiply both sides by one over the coefficient of x:

\displaystyle \frac{1}{5} \times 40 = \frac{1}{5}\times 5\; x.

x = 8.
