I’m confused can someone help?
tia_tia [17]

Answer:

(a) check the first one, and the second one

(b) check the last one

Step-by-step explanation:

This is quite easy actually.

<h2>(A)</h2>

3x+24 = 3 * x + 3 * 8

3(x+8) using distribute property.

3x + 24

You cannot simplify 3x+24 any further

And 3(8x+1) just doesn't work

since it's multiplying

The "*" is an X sign

<h2>(B)</h2>

The first, second, and third are not correct

But the last one is.

I hope this helps!


g(x)= ax^2 + 24


g(4)= 8, g(-4)


a(4^2) + 24 = 8


16a+24= 8

-24 -24

16a = -16

a = -1

(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}.
