Step-by-step explanation:

Missing leg of triangle:

√15²-12²= √225-144=√81=9

Triangle faces= 2*1/2*12*9= 108

Base= 20*9= 180

Front face= 20*15= 300

Back face= 20*12= 240

Total= 108+180+300+240= 828

Okay! Volume of a box is height times width times length. Basically, multiply all of your numbers together.

To celebrate a diners anniversary, the owners have made a 40 foot long sandwich. The sandwich is cut into three unequal pieces.
Ivahew [28]
Let x be he length of middle piece.
3x = length of longer piece.
x-5 = length of shortest piece.

x + 3x + x-5 = 40
5x - 5 = 40
5x = 45
x = 45/5
x = 9. ( Size of middle piece )

Given that the longer piece is 3 times the size of middle piece,

Longest piece = 3 x 9 = 27.

Size of longest piece = 27 feet
Size of middle piece = 9 feet
Size of smaller piece = 40 - (27+9)
= 40 - 36
= 4 feet.
Thank you.

Find the y- intercept and x-intercept of the line. <br><br> 4x-y=8
Darya [45]

Answer:

x-intercept is (2,0)

y-intercept is (0,-8)

Step-by-step explanation:

to find the 'x-intercept', substitute zero for 'y' and solve:

4x - 0 = 8

4x = 8

x = 2;  x-intercept is (2,0)

4(0) - y = 8

0 - y = 8

y = -8; y-intercept is (0,-8)
