If the length of lobby is l and length of seating area is s

First equation is l =s+4 and second is 2s∧2= l∧2 - 16

If we replace l in second equation we get 2s∧2=(s+4)∧2 -16

l=12 and s=8

Correct answer is D

Good luck!!!

Consider this system of equations. Which shows the second equation written in slope intercept form?
lora16 [44]

Answer: Second option.

Step-by-step explanation:

The Slope-Intercept form of the equation of the line is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

You know that the second equation of the System of equations given in the exercise is:

10(x+\frac{3}{5})=2y

Then, you need to solve for the variable "y" in order to write it in Slope-Intercept form. The steps are:

1. Apply the Distributive property and simplify:

10x+\frac{30}{5}=2y\\\\10x+6=2y

2. Now subtract 6 from both sides of the equation:

10x+6-6=2y-6\\\\10x=2y-6

3. Subtract 2y from both sides of the equation:

10x-2y=2y-6-2y\\\\10x-2y=-6

4. Subtract 10x from both sides:

10x-2y-10x=-6-10x\\\\-2y=-10x-6

5. Divide both sides by -2:

\frac{-2y}{-2}=\frac{-10x-6}{-2}\\\\y=5x+3

How to erite a sequence of 1/4 , 1/2,3 write a rule for the sequence 1/4 1/2 3/4
FrozenT [24]
The equation for finding the equation of an arithmetic sequence is an=a1+(n-1)d, where n is the input for the sequence, a1 is the first term, and d is the difference between each term. 

a1= 1/4
d= 1/4 

an= 1/4 + (n-1)(1/2) - First you need to distribute the 1/2 to both the n and -1 to get:    an= 1/4 + 1/2n -1/2.

Then you need to add like terms (1/4-1/2) to get an=1/2n-1/4.  Hope this helps!

Hidden right triangle
28 feet tall (1 leg)
the piece that fell over is the hypotonuse
last leg is what we need to find

81-28=53


a²+b²=c²
a and b are legs and c is the hypotonuse

given
on leg is 28 and the hypotonuse is 53
th othe leg is b
28²+b²=53²
784+b²=2809
minus 784 from both sides
b²=2025
sqrt both sides
b=45

answer is 45ft

Round to the nearest hundredth 5/8
Solnce55 [7]
Eighths and their multiples are common fractions which I recommend memorizing, but to actually solve this, you use the literal meaning of a fraction and divide 5 by 8. See the long-division below (it was surprisingly difficult to type, so I hope it helps!).

To round 0.625 to the nearest hundredth, we go to the second decimal place, which is 5, so we round up to 0.63.
