The rectangle and the trapezoid have the same area. What is the length l of the rectangle?

l=
ft

Answers

The nacer is 66 or67 not that shere

The length 'l' of the rectangle will be;

⇒ l = 18 feet

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The rectangle and the trapezoid have the same area.

Now,

Since, The rectangle and the trapezoid have the same area.

Hence, We get;

Area of rectangle = l × 9

And, Area of trapezoid = 1/2 (24 + 12 ) × 9

= 1/2 × 36 × 9

= 18 × 9

= 162

So, We get;

⇒ l × 9 = 162

⇒ l = 162/9

⇒ l = 18 feet

Thus, The length 'l' of the rectangle will be;

⇒ l = 18 feet

8=f-(13-2)
???? help

Answers

Answer:

I got you

Step-by-step explanation:

f= 19

Simplifying
8 = F + -1(13 + -2)

Combine like terms: 13 + -2 = 11
8 = F + -1(11)

Multiply -1 * 11
8 = F + -11

Reorder the terms:
8 = -11 + F

Solving
8 = -11 + F

Solving for variable 'F'.

Move all terms containing F to the left, all other terms to the right.

Add '-1F' to each side of the equation.
8 + -1F = -11 + F + -1F

Combine like terms: F + -1F = 0
8 + -1F = -11 + 0
8 + -1F = -11

Add '-8' to each side of the equation.
8 + -8 + -1F = -11 + -8

Combine like terms: 8 + -8 = 0
0 + -1F = -11 + -8
-1F = -11 + -8

Combine like terms: -11 + -8 = -19
-1F = -19

Divide each side by '-1'.
F = 19

Simplifying
F = 19

Answers

Answer:

angle JKL= 54 degrees

Step-by-step explanation:

look they are congruent

(2x+5)=(3x-6)

x=11

then plug in

2x+5

2(11)+5

=27

then

3x-6

(3)(11)−6

=27

Both are congruuent

27+27=54

the answer is 54 because if you complete 2x+5=3x-6, x=11 which makes 2(11)+5, which equals 22+5=27, and 27+27 is 54

how would you solve -5(x - 1) = 40

Answers

you would distribute the -5 to the x and the -1, so it would be:
-5x+5=40
you would then subtract 5 from both sides, so you would get:
-5x=35
you would then divide by -5 on both sides, so you would get:
x=-7

Answer:

x = -7

Step-by-step explanation:

Apply the distributed property: -5x - -5 = 40Simplify: -5x + 5 = 40Subtract 5 from each side, so it now looks like this: -5x = 35Divide each side by -5 to cancel out the -5 next to x. It should now look like this: x = -7
