Answer:

x = 15

Step-by-step explanation:

We are given the following equation which we are to solve for x:

$3 x = 4 5$

This is one very simple equation that we need to solve for x.

For that, we will divide both sides by 3 to isolate x and make it the subject of the equation to get:

$\frac { 3 x } { 3 } = \frac { 4 5 } { 3 }$

$x = 15$

Answer:

x=15

Step-by-step explanation:

3x=45

We want to get x by itself, so we divide each side by 3

3x/3 = 45/3

x =15

Suppose a pizza must fit into a box with a base that is 12 inches wide.

mojhsa [17]

The area of the whole pizza must be at most 113.10 square inches in order to perfectly fit in the box. The values of r represent the half of the length of the pizza with respect to its center. In this case, the r must not exceed 6 inches (r ≤ 6 inches) in order to fit in the pizza box. On the other hand, the values of a represent the total area the pizza will occupy. In this case, the a must not exceed 113.10 square inches (a ≤ 113.10) in order to house the pizza perfectly.

Please ASAP help please !!! Help me anyone

difference of squares means that both the terms are square terms. (also there must be a - symbol)

for example

y^2 - 4

square root of y^2 is y

square root of 4 is +2 as well as -2

so you would factorise it like this:

(y+2)(y-2)

1. y^4 has a square root of y^2 as y^2 × y^2 is y^4.

however, -2 doesnt have a whole number square root so it is not a difference of squares.

2. 25 has a square root of 5. m^2 has a square root of m. n^4 has a square root of n^2. so this 25m^2n^4 is a square term.

1 has a square root of +1 and -1.

therefore, this one is a difference of squares. (5mn^2 +1) (5mn^2 -1)

3. p^8 has a square root of p^4. q^4 has a square root of +q^2 and -q^2)

so it is a difference of squares. (p^4+q^2)(p^4 -q^2)

4. 16x^2 is a square term as irs square root is 4x.

however, 24 is not a square term.

therefore, it is not a difference of squares.
