Answer:

(x-3) is the correct expression

Step-by-step explanation:

To factor you split the expression apart -

x² + 2x – 15

This breaks up to (x+5)(x-3)

If you multiply (FOIL) these you get your expression x² + 2x – 15

Your answer choices do not include (x+5) so it must be (x-3)

I hope this helps!

A car was sold 24 standard washed in a day , which was 25% of their total sales for that day . What was the total amount of wash

-Dominant- [34]

Answer:

$96$

Step-by-step explanation:

GIVEN: A car was sold $24$ standard washed in a day , which was $25\%$ of their total sales for that day.

TO FIND: Total amount of washes that the car wash sold that day.

SOLUTION:

Let the total sales of car washes sold for that day $=x$

total number of standard car washes sold $s=24$

As, total standard car washes sold are $25\%$ of total sales in a day

$s=\frac{25}{100}x$

putting value in equation

$24=\frac{25}{100}x$

$x=\frac{24}{25}\times100$

$x=96$

Hence the total number of car washes sold that day are $96$
