Answer:

Prime

Step-by-step explanation:

x² + 25 is prime (unfactorable).

Here's what the other options come out to:

(x + 5)(x + 5) = x² + 10x + 25

(x + 5)(x − 5) = x² − 25

(x − 5)(x − 5) = x² − 10x + 25

melisa1 [442]

Answer:

£1,120

Step-by-step explanation:

The computation of the total money earned is given below:

Given that

Ratio of children to adult be 2;3

There is 80 children

each adult cost is £8

And for children it is quarter of adult i.e £8 ÷ 4 = £2

For children there is an earning of

= 80 × £2

= £160

And, for adult it would be

but before that the number of adults be

Let us assume the number of adults be x

$\frac{2}{3} = \frac{80}{x}$

After cross multiplication, the number of adult be 120

So the adult earning be

= 120 × £8

= £960

So, the total money made would be

= £960 + £160

= £1,120

How do you solve this?

algol [13]

Answer:

It's asking for you to calculate the volume of a cylinder and multiply it by 2/3. This is because the question is asking how much water is in a cylindrical vase with the height and radius.

The formula to calculate the volume of a cylinder is : 3.14 (r^2) (h)

R being the radius and H being the height.

Plug in the values then multiply it all by 2/3

Hoped this help you solve your problem.

Determine which ordered pairs fall on the graph of f(x) = -2x-1 Show all of your work for each ordered pair. Ordered Pairs: (1,1

LiRa [457]

Answer:

(1, 1) is the only one on the graph

Step-by-step explanation:

To determine if an ordered pair lies on the graph, substitute the x-coordinate of the ordered pair into f(x) and evaluate. If the value equals the y-coordinate of the ordered pair then it lies on the graph

f(1) = (2 × 1) - 1 = 2 - 1 = 1 ⇒ (1, 1) lies on graph

f(- 1) = (2 × - 1) - 1 = - 2 - 1 = - 3 ≠ - 4 ⇔ (- 1, - 4 ) not on graph

f(- 2) = (2 × - 2) - 1 = - 4 - 1 = - 5 ≠ - $\frac{1}{8}$ ⇒ (- 2, - $\frac{1}{8}$ ) not on graph
