Answer:

Step-by-step explanation:

Remark.

I take it we are only concerned with the deep lime face that we can see closest to us.

Construction

Draw one line that goes from the right of the left foot up to the 18 foot line

Draw another line that goes from the left of the right foot up to the 18 foot line.

label the width of the right foot as 18 - 6 - 6 = 6

Solution

Right foot

Area = L * w

L = 12 feet

w = 6 feet

Area = 12*6 = 72

Left foot (same area) 72

Area above the door.

Height = 12 - 6 = 6

width 6

Area = 6 * 6 = 36

Answer: Total Area = 72 + 72 + 36 = 180

Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly. Find the errors in her solution. What should her answer have been?

Irina-Kira [14]

Answer: The correr solution is $x=\frac{17}{34}$

Step-by-step explanation:

Since the steps in Lin's solution are not shown, we are not able to find her erros. However, we can solve it step by step and find the correct result:

$8(x-3)+7=2x(4-17)$

Firstly, in the left part of the equation we have to multiply $8$ by the numbers inside the parenthesis; and in the right side we have to solve first what is inside the parenthesis:

$8x-24+7=2x(-13)$

Adding similar terms in the left side and multiplying $2x$ by the number inside the parenthesis in the right side:

$8x-17=-26 x$

Isolating $x$ :

$x=\frac{17}{34}$ This is the correct solution

Turn -2x+4y=0 into slope-intercept form

yanalaym [24]

Y=1/2x +0. You add the 2x to the other side, and then divide everything by 4 to have only 1y.

In the alphabet, x comes before y. Use this fact to describe a method for remembering how to write ordered pairs.

Fofino [41]

Answer:

Step-by-step explanation:

so when remembering how to write ordered pairs, think of the monkey bars. you have to get there before you can climb up, x being walking to the monkey bars and y being climbing up them. Think of the steps to get to the monkey bars compared to the fact that x is before y. getting to the monkey bars comes before climbing them, is x (run) and climbing them would be y (rise), and not the other way around because like the question said; x comes before y.

I really hope this wasn't too confusing. I'm really sorry if it was!

Hope this helps! :)
