What is x*x=15? (Basically make an equation that equals up to 15.)
rodikova [14]

Answer:

\displaystyle \sqrt{15} = x

Step-by-step explanation:

Be VERY careful. When it write out the equation that way, it will give the speculation of this:

\displaystyle 15 = x^2

Now, in this case, since you were extra explanatory about this [what is written in parentheses], two factors I know of that multiply to 15 are these:

** \displaystyle 15 = 2 \times 7\frac{1}{2}

I am joyous to assist you at any time. ☺️

Answer:

625 cm3

Step-by-step explanation:

Formula V1 * P1 = V2 * P2

V1 = 450 cm3

P1 = 125 kPa

P2 = 90 kPa

V2 = ?

V2 = (V1 * P1) / P2

V2 = (450 cm3 * 125 kPa) / 90 kPa = 625 cm3

Suppose you have a $15 coupon that can be used on any purchase over $100 at your favorite clothing store. The discounted price o
victus00 [196]
Given that a coupon for $15 off will be applied on purchases over $100, the given discounted price of the jacket is $203. Since this is the discounted price, then it should be the price after the coupon has been used. To find the retail (or original) price, we simply add 15 back to 203. So the retail price should be $218.

How do i factor the coefficent out of a variable, such as 2.4n+9.6 and -6z+12
ANEK [815]
You are factoring one or more linear expressions (but are not factoring variables).

2.4n+9.6 can be divided by 2.4 and then the result mult. by 2.4:

2.4n+9.6 = 2.4 [ n + 4 ]

Also:  -6z+12= 6 [ -z + 2 ]  Here I have simplified linear functions but factoring out common constant coefficients (not variables).
