Answer:

Length = 45/4 inches

Width= 15/4 inches

Step-by-step explanation:

Perimeter= 30 inches

Let width = x

Length = 3x

Perimeter = 2l + 2w

30= 2(3x) + 2(x)

30 = 2(3x+x)

30/2 = 3x+x

15 = 4x

x= 15/4

Hence width is 15/4

Then the length must be 3x = 3(15/4)

THEREFORE, Length = 45/4 inches

Width= 15/4 inches

Hope this helps!

Answer:

$2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)$

Step-by-step explanation:

The formula for the area of a triangle is $\frac{1}{2} *b*h$

The triangles that can be made is the triangle that has legs 20 and 50 and the triangle that has legs 20 and 10.

Since there are 2 of each triangles, we get:

$2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)$

The answer that fits is the first option.

Graph 4x +3x=11 and x=y+1 as 2 separate lines that intersect.

vichka [17]

Answer:

Step-by-step explanation:

So first of all, you can rearrange your equations:

4x + 7x = 11 can be rearranged and simplified to x = 11/7

x = y + 1 can be rearranged to y = x - 1

Then you can graph them like normal by plugging in points. It should look like the following picture
