The expression is equivalent to this expression is  2x^2+3x.

The correct option is A.

Given

The expression is;

= x(2x + 3)

<h3>What is the algebraic expression?</h3>

Algebraic expressions consist of numbers and variables along with operational signs.

The equivalent expression is found by multiplying x and simplifying.

Therefore,

The expression is equivalent to this expression is;

\rm = x(2x + 3) \\\\= 2x\times x+ 3 \times x\\\\= 2x^2+3x

Hence, the expression is equivalent to this expression is  2x^2+3x.

Answer:

You multiply 5 by 1/5 to get 1. So with 2x, you multiply by 1/(2x) to get 1. That's about all you know, since we only know that x is positive.

Step-by-step explanation:

Hope it helps

For question 4, x = 18 units,

For question 5, x = 8.333 units.

Step-by-step explanation:

Step 1:

Since the given polygons are similar to each other, all the ratios of one polygon to the other will remain equal for all the values of the two similar polygons.

We take the ratio of the same sides of both polygons i.e. the ratio of the lengths or the ratio of the widths.

Step 2:

For question 4, the first rectangle has a length of 9 units while the width is 3 units.

For the second rectangle, the length is x as x is greater than the width in the first rectangle. The width is 6 units.

The ratio of the first rectangle to the second is;

\frac{3}{6} : \frac{9}{x} , x = (9)(\frac{6}{3} ) = 18. So x = 18 units.

Step 3:

The shapes in question 5 are made of a square and a triangle.

For the first shape, the side length is 6 units while the side of the triangle is 10 units.

For the second shape, the side length is 5 units while the side of the triangle is x units.

The ratio of the first shape to the second is;

\frac{6}{5} : \frac{10}{x} , x = (10)(\frac{5}{6} ) = 8.333. So x = 8.333 units.
