Ahh ok so split it up into two rectangles:

Rectangle one:
A=lw
A=4(12)
A=48

Rectangle two:
A=lw
A=10(2)
A=20

Add both areas up to get 68 ft squared!! :)

Answer:

68 square feet.

Step-by-step explanation:

My way of doing it is to first, split the shape where the length is different so it would be easier to solve. That means you should have the bottom part of the shape split from the whole shape, which makes 2 rectangles. The bottom rectangle should have the length of 2 feet, and the width of 10 feet on both parallel sides. The top rectangle should have the length of 4 feet, and the width of 12 feet on both parallel sides.

Next, you multiply both rectangles by their width and length. For example, first start with the first rectangle on the top. You should multiply the length, 4 feet by the width, 12 feet. Then, for the bottom rectangle, multiply the length, 2 feet by the width, 10 feet.

1.) 4 x 12 = 48

2) 2 x 10 = 20

Lastly, add the two numbers to get the answer.

48 + 20 = <u>68</u>

A line passes through the point (-1,-5) and has a slope of -5.

Anna71 [15]

<h3>hello!</h3>

We're given a point that the line intersects and its slope.

Let's use Point-slope:-

$\boxed{y-y1=m(x-x1)}$

y1 = -5

m=-5

x1=-1

$\boxed{y-(-5)=-5(x-(-1)}$

$\boxed{y+5=-5(x+1)}$

Convert to slope-intercept:-

$\boxed{y+5=-5x-5}$

$\boxed{y=-5x-5-5}$

Finally,

$\bigstar{\boxed{\pmb{y=-5x-10}}$

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

For the function f(x)=5x2−5x, evaluate and simplify.

Marianna [84]

Answer:

10x -5 +5h

Step-by-step explanation:

Use the function definition with the given arguments.

$\dfrac{f(x+h)-f(x)}{h}=\dfrac{(5(x+h)^2-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{(5(x^2+2hx+h^2)-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{5x^2+10hx+5h^2-5x-5h-5x^2+5x}{h}=\dfrac{10hx-5h+5h^2}{h}\\\\=\boxed{10x-5+5h}$

Given klmn is a trapezoid, kl = mn, m<1 = m<2, lm/kn = 8/9, pklmn = 132. Find: the length of the legs

Ilia_Sergeevich [38]

Answer:

The length of legs lm, mn, and lk is 32 while that of kn is 36.

Step-by-step explanation:

The diagram is attached in the answer.

As both the angles are equal thus the two forms isosceles triangles. This is true because the converse of base angle theorem is applicable here. The theorem clearly states that when a trapezoid is divided by the diagonal, it forms two set of angles where m<1=m<2 and m<lmk=m<nmk

This leads the two set of legs such as

$\dfrac{lm}{kn}=\dfrac{8}{9}$
