3(6x+8)=24+18x what the answer
Answer:
0=0 or as known as infinite solution
Step-by-step explanation:
when answering a type of question there are 3 steps
1) Distribute: 3(6x+8)=24+18x
3 x 6x= 18x 3 x 8= 24
18x +24 = 24 + 18x
2) Subtract 24 from both sides of the equation:
18x + 24 = 24 + 18x
-24 -24
18x + 0 = 0 + 18x
3) Subtract 18x from both sides to set apart (x) : 18x = 18x
-18x -18x = 0 = 0

Brianna's parents built a swimming pool in the backyard. Brianna says that the distance around the pool is 120 feet.
40 Ft
2011
1. Is she correct? Explain why or why not. (Your explanation needs to include the following: If she is correct, show what she
did to find the distance around the pool. If she is not correct, find the correct distance, showing all work.)
2. Explain (using words this time) how Brianna would determine the distance around the pool so that her parents would
know how many feet of stone to buy for the edging around the pool.
No, Brianna is not correct.
The distance around the pool is 131.4 ft
What is perimeter of semicircle?The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius, and, 2r=d is diameter.
P=(πr + 2r)
here, we have,
1) Semi circle with a diameter equal to the side opposite it, 20 ft.
Find the length of half the circle:
Circumference of semi-circle = (1/2)(πd)
Where:
π = 3.14
d = 20 ft.
Circumference of semi-circle = (1/2)(3.14)(20 ft) = 31.4 ft.
2) Vertical lengths from the endpoint of semi-circle to the endpoints of horizontal lengths, 40 ft each ⇒ 2 × 40 ft. = 80 ft.
3.) Horizontal length at 20 ft.
Add the semi-circle, vertical, and horizontal lengths:
Distance around the pool = 31.4 ft + 80 ft. + 20 ft.
Distance around the pool = 131.4 ft.

find m<1 m<2 138
i did it asappp,thank you
Answer:
mΔ1 = 42°
mΔ2 = 42°
Step-by-step explanation:
Δ1 + 138° = 180°
Δ1 = 180° - 138°
Δ1 = 42°
______________Δ2 + 138° = 180°
Δ2 = 180° - 138°
Δ2 = 42°

XZW XYV find the perimeter of XZW?
PLS HELP
9514 1404 393
Answer:
180 units
Step-by-step explanation:
The perimeter of ∆XYV is ...
Pxyv = XY +YV +VX
Pxyv = 29 +31 +40 = 100
The triangles are similar, so the scale factor from ∆XYV to ∆XZW applies to the perimeter. That scale factor is ...
WX/VX = (32+40)/40 = 1.8
Then ...
Pxzw = 1.8 × Pxyv = 1.8 × 100
Pxzw = 180 . . . units

Andy cycles a distance of 30 km at an average speed of 24 km/h. He then runs a distance of 12 km at an average speed of 8 km/h.
Work out the total time Andy takes. Give your answer in hours and minutes.
Answer:
1 Hour and 20 minutes
Step-by-step explanation:
Time = Distance ÷ Speed
The total time taken by Andy is (1.25 + 1.5) 2.75 hrs or 165 minutes and this can be determined by using the formula of speed.
Given :
Andy cycles a distance of 30 km at an average speed of 24 km/h. He then runs a distance of 12 km at an average speed of 8 km/h.The formula of speed is used to determine the time taken by Andy to cover the total distance. The formula of speed is given by:
[tex]\rm s = \dfrac{D}{t}[/tex]
where 's' is the speed, 'D' is the distance and 't' is the time.
Now, the time taken by Andy to cover the distance of 30 Km with the speed of 24 Km/hr is:
[tex]\rm 24 = \dfrac{30}{t}[/tex]
[tex]t = \dfrac{30}{24}[/tex]
t = 1.25 hrs.
Now, the time taken by Andy to cover the distance of 12 Km with the speed of 8 Km/hr is:
[tex]\rm 8 = \dfrac{12}{t}[/tex]
[tex]t = \dfrac{12}{8}[/tex]
t = 1.5 hours.
So, the total time taken by Andy is (1.25 + 1.5) 2.75 hrs or 165 minutes.
