Let the number be x, then 5 + 1/4 x = 2/3 x
2/3 x - 1/4 x = 5
5/12 x = 5
5x = 5(12)
x = 12

(4) 64 tiles, (5) $\mathrm{N}=\mathrm{s}^{2}$ , (6) $N^{2}=S^{4}$

Step-by-step explanation:

Given data: Side length of square tile = 1 ft

(4) Side length of square pool = 8 ft

$\text {Number of tiles} =\frac{\text { Area of square pool }}{\text { area of square tile }}$

$=\frac{8 \times 8}{1 \times 1}$

= 64

Hence 64 tiles needed for the border.

(5) Suppose number of square tiles be N and side of square tub is s ft.

So, N = $\frac{s \times s}{1 \times 1}$

$\Rightarrow N=s^{2}$

So, the expression is $\mathrm{N}=\mathrm{s}^{2}$ .

(6) The equivalent expression is $\mathrm{N}^{2}=\mathrm{S}^{4}$ .

The cubic polynomial below has a double root at r4 and one root at x = 6 and passes Through the point (2, 36) as shown. Algebrai

qaws [65]

The graph in the question is missing.

Answer:

y = $\frac{-1}{4}( x^3 + 2x^2 - 32x -96)$

Step-by-step explanation:

The function is cubic

It has roots as -4, -4 , 6

this means the value of x = -4, -4 , 6 which makes the entire equation zero

so we have solutions as

x+4 = 0

x- 6 = 0

on forming a cubic equation using these

(x+4)(x+4)(x-6)

the equation passes through (2,36)

put x = 2

(2+4)(2+4)(2-6) = (6)*(6)*(-4)

which exceeds 36 so we product the equation with -1/4 to get 36

Final equation

y = $\frac{-1}{4} (x+4)(x+4)(x-6)$

y = $\frac{-1}{4}( x^3 + 2x^2 - 32x -96)$
