Answer:

4x÷(5+x)÷ [6x÷(x+2)]= 4x × (x+2) ÷ [(5+x)(6x)]

= 2×(x+2) ÷ [3(5+x)]

= 2x+4/3x+15

= 2(x+2)/3(x+5)

How many dimensions does a line segment have

Natalija [7]

Answer:

A line segment has one dimensions.

Step-by-step explanation:

A line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints.

Dimension is an aspect or feature of an object.

A line segment, let us say AB has two endpoints and has only one measurable feature that is its length which is actually the distance between the two end points A and B.

Hence, a line segment is one-dimensional.

Let u = <-8, -9>. Find 7u. (2 points)

ANEK [815]

Multiplying a vector by a scalar means to multiply each coordinate of the vector by said scalar.

So, we must multiply both entries by 7:

$u=(-8, -9)\implies 7u=(-8\cdot 7, -9\cdot 7) = (-56, -63)$

After reading a book foe English class, 100 students were asked whether or not they enjoyed it. Nine twenty-fifths of the class

Katena32 [7]

Answer:

The number of students who liked the book was 64.

Step-by-step explanation:

After reading a book for English class, 100 students were asked whether or not they enjoyed it.

Now, given that nine twenty-fifths of the class did not like the book.

So, $\frac{9}{25}$ of the whole class did not like the book.

Then, the fraction of the class who did like the book was $(1 - \frac{9}{25}) = \frac{16}{25}$ .

Therefore, the number of students who liked the book was $(100 \times \frac{16}{25}) = 64$ . (Answer)
