Answer:

Segment BF = 15

Step-by-step explanation:

Segment DE is parallel to segment BC

Segment EF is parallel to segment AB.

Because segment EF is parallel to segment AB, triangles ADE and EFC are proportional. We must find the scale factor which these two triangles are proportional.

24 ÷ 20 = 1.2

Scale Factor = 1.2

18 ÷ 1.2 = 15

Segment EF is parallel to segment AB so segment EF is congruent to segment DB.

hope this helps! ps. im very sorry about the previous wrong question, but i hope this is right (,,>﹏<,,) xx

Answer:

270 cm^2

Step-by-step explanation:

This is quite easy.

There is formula for it, the formula is bh/2

b= is the base or side that the triangle's altitude or height is perpendicular to.

h= is the height of the triangle or the altitude of the triangle.

I can always like to thing that a triangle is like half of a rectangle because the area for a rectangle is bh, but in a triangle it is half the bh.

b= 30

h=18

Now substitute the values in the formula

30(18)/2

30 times 18 = 540

divide the product by 2

540/2 = 270

Which graph shows the solution to the system of linear inequalities? y ≥ 2x + 1 y ≤ 2x – 2

Artyom0805 [142]

Answer:

Step-by-step explanation:

Given the two inequalities:

$y \ge 2x + 1\\ y \le 2x - 2$

To graph them, first of all, let us write their corresponding equations:

$y = 2x + 1 \\y = 2x - 2$

We now find at least 2 points each which satisfy the equations to plot the graph.

Equation $y = 2x + 1$ :

Putting x = 0, y = 1

Putting y = 0, x = $-\frac{1}2$ .

Two points are (0, 1) and ( $-\frac{1}2$ , 0).

Equation $y = 2x -2$ :

Putting x = 0, y = -2

Putting y = 0, x = 1.

Two points are (0, -2) and (1, 0).

Now, let us plot them.

Let us take a point (1, 4) and check whether it satisfies the first inequality.

$4 \ge 2 \times 1 +1\\\Rightarrow 4 \ge 3$

Which is true.

So, The shaded region will be towards point (1,4).

Let us take a point (1, 4) and check whether it satisfies the second inequality.

$4 \le 2 \times 1 -2\\\Rightarrow 4 \le 0\ [\bold{False}]$

So, The shaded region will be opposite to point (1,4).

Please refer to the attached graph for the answer.

No solution exists for them because there is no common shaded region.
