Answer:

x=13, A=169

P=4s, so you substitute P with 52 and you're left with 52=4a. You divide 4 to both sides of the equation and a(or x) equals 13.

A=s^2, so since your side(x) equals 13 you calculate 13^2 or 13×13, and A=169.

Answer:

13 = x

169 in^2 = A

Step-by-step explanation:

Since perimeter is given as 52 in we can find x by dividing 52 by 4 because the area is calculated by adding all side lengths together

52 ÷ 4 = x

13 = x

The area is calculated by multiplying height to the base , the height given here is 13 and since this is a cube it has all side lengths in equal measure therefore the area for thid shape is

13 × 13 = 169 in^2

What is the slope-intercept equation of the line below?

Nataly [62]

Answer:

Step-by-step explanation:

We will use the 2 coordinates marked on the graph as the reference.

The coordinates are:

A(4,-2)

B(0,3)

We know that the standard form for equation of line is:

y = mx+c

where m is the slope of the equation

and c is the y-intercept.

Very clearly, the y-intercept is where the line intercepts the y line.

and in this case, y-intercept = c = 3.

Now we know that the equation of line is now

y = mx + 3

To find m, the slope, we can use the 2 above coordinates.

slope of line = $\frac{y1-y2}{x1-x2} \\=\frac{-2-3}{4-0} \\=\frac{-5}{4} \\=-\frac{5}{4}$

(Note: There is a 2nd way to find the slope in this case, let me know if you are interested to find out.)

Equation of line: $y=-\frac{5}{4} x+3$

Therefore the answer is D.

If an object falls 40 meters in 4 seconds,how far will it fall in6 seconds

sweet [91]

Answer:

60 seconds

Step-by-step explanation:

step 1.) find how many meters it falls per second

40m / 4sec = 10m/s

step 2.) use the equation above to find in terms of the question

10m/s for 6sec = 10 x 6 ====> 60 seconds

iren2701 [21]

Paige is ahead of kate. It dosen't say she is behind anyone or last in the line. Carlos is not first in line. Kate cannot be first because someone is ahead of her. And lisa is last. So the answer is definitely paige. Hope i helped. Have a nice day.

Ac is tangent to circle o at point c what is the length of ac?

MissTica

Answer:

The Answer is 12

Step-by-step explanation:

Use Pythagorean theorem. AB=8 and BO=5 We still need to find AO

AO=AB+BO

8+5

AO=13

Now solve for AC

AC^2 + OC^2= AO^2

AC^2+5^2=13^2

AC^2+ 25=169

AC^2=144

AC= 12
