No, x = 15 is not an algebraic expression; it is actually an algebraic equation. There is an equal sign present in an equation, but not an expression. Hope this helps! :)

No it isn't because it wasn't an expression. An algebraic expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide)

Find the perimeter and area of each figure.

Sergio039 [100]

Answer:

1. A = 2x; P = 4x+2. A = 4; P = 10.

2. A = y² +2; P = 4y +2. A = 27; P = 22.

Step-by-step explanation:

1. The area is the sum of the marked areas of each of the tiles:

A = x + x

A = 2x

The perimeter is the sum of the outside edge dimensions of the tiles. Working clockwise from the upper left corner, the sum of exposed edge lengths is ...

P = 1 + (x-1) + x + 1 + (x+1) + x

P = 4x +2

When x=2, these values become ...

A = 2·2 = 4 . . . . square units

P = 4·2+2 = 10 . . . . units

_____

2. Again, the area is the sum of the marked areas:

A = y² + 1 + 1

A = y² +2

The edge dimension of the square y² tile is presumed to be y, so the perimeter (starting from upper left) is ...

P = y +(y-2) +1 +2 +(y+1) +y

P = 4y +2

When y=5, these values become ...

A = 5² +2 = 27 . . . . square units

P = 4·5 +2 = 22 . . . . units

Josh is a software salesperson. His base salary is 2200$ and he makes 70$ more for everycopy of history is fun he sells. What is

natta225 [31]

Answer: $\$3,740$

Step-by-step explanation:

You know that Josh's base salary is:

$base\ salary=\$2,200$

And, according to the information given in the exercise, Josh makes $70 more for every copy he sales.

Knowing this you can determine that his total pay will be the sum of his base salary and the podruct of $70 and the number of copies.

Therefore, if Josh sells 22 copies, then we get that his total pay is:

$Total\ pay=\$2,200+(22)(\$70)\\\\Total\ pay=\$3,740$
