I’m confused can someone help?

Answer:

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

(b) check the last one

Step-by-step explanation:

This is quite easy actually.

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

The first, second, and third are not correct

But the last one is.

For the function g defined below, a is a constant and g(4)=8. What is the value of g(-4)?

Travka [436]

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 $\mathrm{N}^{2}=\mathrm{S}^{4}$ .
