(Once again I am doing this question because no one answered it last time. thanks)

This question, because it is worded strangely, is asking for her salary before taxes. We can figure this out because we are given an expression, "(9/10)s", which represents what we want to find.

The equation would be either:
(9/10)s = 486
or
0.9s = 486

To solve, you would divide 486 by 0.9, which gives you $540.

I hope this helps!

The length of a rectangle is (x + 1) cm and its width is 5cm less than its length.

NeX [460]

Answer:

a) the area of a square is in terms of x is

$(x+1)^2$ centimeter square

b)The length of the rectangle is l = (x+1)

l = 7+1 =8 cm

The width of the rectangle is w = [(x+1)-5]

w = (7+1)-5 =3 cm

Step-by-step explanation:

a) the area of a square is in terms of x is

area of square is $l^{2} = (x+1)(x+1)$

= $(x+1)^2$

b) Given length is l = (x+1) cm and

the width is 5 cm less than its length.

so we have take width is w = (x+1)-5 cm

Given area of triangle is 24 cm

Area of rectangle = length X width

24 = (x+1)(x+1 -5 )

now simplification $24 = (x+1)^2 - 5 (x+1)$

apply (a+b)^2 = a^2+2 a b+b^2

$x^2+2 x+1-5 x-5 =24$

$x^2 -3 x -4-24=0$

$x^{2} -3 x -28 =0$

now find factors of 28 = 7 X 4 is

$x^{2} -7 x+4 x-28=0$

$x(x-7)+4(x-7)=0$

$(x+4)(x-7)=0$

x = -4 and x=7

there fore you have to choose x = 7

The length of the rectangle is l = (x+1)

l = 7+1 =8

The width of the rectangle is w = [(x+1)-5]

w = (7+1)-5 = 3

Verification:-

Given area of rectangle = 24 = 8 X 3

24 =24

so we can not choose x=-4

we have to choose x =7 only

Select the correct answer from each drop-down menu.

RSB [31]

Evidence are simply facts to support a claim, while counterexamples are instances to show the contradictions in a claim

The question is incomplete, as the required drop-down menus are missing. So, I will give a general explanation

To show that a statement is true, you need evidence.

Take for instance:

$\mathbf{if\ a^2 = 4,\ then\ a = 2}$

The evidence that the above proof is true is by taking the squares of both sides of $\mathbf{a = 2}$

$\mathbf{a^2 = 2^2}$

$\mathbf{a^2 = 4}$

However, a counterexample does not need a proof per se.

What a counterexample needs is just an instance or example, to show that:

$\mathbf{if\ a^2 = 4,\ then\ a \ne 2}$

An instance to prove that: $\mathbf{if\ a^2 = 4,\ then\ a = 2}$ is false is:

$\mathbf{a = -2}$

Hence, the complete statement could be:

In a direct proof, evidence is used to support a proof . On the other hand, a counterexample is a single example that shows that a proof is false.
