Which polynomial can be simplified to a difference of squares? 10a2 + 3a – 3a – 16 16a2 – 4a + 4a – 1 25a2 + 6a – 6a + 36 24a2 – 9a + 9a + 4

Answers

16a² - 4a + 4a - 1 can be simplified to a difference of squares:

16a² - 4a + 4a - 1 =
16a² - 1 =
(4a)² - 1² =
(4a-1)(4a+1)

Answer:

2. $16a^2-4a+4a-1$

Step-by-step explanation:

We have to find the polynomial can be simplified to a difference of squares.

1. $10a^2+3a-3a-16$

Combine like terms

$10a^2-16$

10 in $10a^2$ is not a perfect square number because when a number end with one zero then the number is not perfect square number.

Therefore, it can not be simplified to a difference of squares.

2. $16a^2-4a+4a-1$

$16a^2-1$

Combine like terms

$(4a)^2-(1)^2$

Hence, the polynomial can be simplified as difference of squares.

3. $25a^2+6a-6a+36$

Combine like terms

$25a^2+36$

$(5a)^2+(6)^2$

Hence, the polynomial can not be simplified as difference of squares because the polynomial can be simplified as sum of squares.

4. $24a^2-9a+9a+4$

Combine like terms

$24a^2+4$

$24a^2+(2)^2$

$24=2* 2* 3* 2$

24 is not a perfect square number because when factorize 24 then 2 and 3 are not paired.

Hence, the polynomial can not be simplified as difference of squares.

Which shows the equation c=a(w/150) correctly solved for the variable w ?

Answers

$c=a( (w)/(150) )$

$c=a* (w)/(150)$ $Simplify \ brackets$

$c= (aw)/(150)$

$c*150=aw$ $Multiply \ both \ sides \ by \ 150$

$150c=aw$    $Regroup \ terms$

$(150c)/(a) = w$    $Divide \ both \ sides \ by \ a$

$w= (150c)/(a)$    $Solution$

Final answer:

To solve the equation c = a(w/150) for 'w', divide the equation by 'a' and then multiply by 150. This gives us w = 150c/a. This equation represents 'w' in terms of 'c' and 'a'.

Explanation:

To solve the equation c = a(w/150) for the variable w, you need to isolate w on one side of the equation. The goal is to express w in terms of c and a.

First, divide both sides of equation by a. This gives you c/a = w/150.
Then, multiply both sides by 150 to solve for w. This results in w = 150c/a.

So, the equation solved for w is w = 150c/a.

Craig has £13.40 he sees this offer in a restaurant :main courses £8.90 each.Buy one main course and get the second half price. Can he afford to buy two main courses?Show your working

Answers

Answer:

Yes

Step-by-step explanation:

Full price for first course: £8.90

Half price: £4.45

One and one half times

full price is then: £13.35

Since this is less than Craig's £13.40, he can just barely afford to buy two main courses at these prices.

What is 7/8 x c for c=8

Answers

Answer:
7

Explanation:
We are given the equation:
$(7)/(8)$ * c

We want to get the value of the equation at c = 8.
Therefore, all we have to do is substitute c in the equation with 8 and solve as follows:
$(7)/(8)$ * 8

= $(7*8)/(8)$

The 8 in the numerator will be cancelled out with the 8 in the denominator leaving us with only the 7 as a solution

Hope this helps :)

Answer:

Value is 7

Step-by-step explanation:

We are given the expression, $(7)/(8)* c$ .
