You have to use
a ^{2}   +  b ^{2}  = c ^{2}
so take your 12in in height and use it as your
a^{2}
divide 10 in half to make your base so now your
b^{2}
is 5. now you have to add 12 and 5. this gives you 17. now square root it.
\sqrt{17}
your answer in now. 4.12. since you have 2 triangles in one whole triangle add 4.12 to 4.12 and you get 8.24. your pyramid has 4 triangles so
4 \times 8.24
is 32.98.

10×10 is 100 so add 32.98 to it.

your surface area is 132.98

Solve the system by the substitution method.<br> x-2y = -2<br> y = - 3x + 8
aliina [53]

x-2y = -2

x-2(-3x+8)=-2

mutiply the bracket by -2

(-2)(-3x)=6x

(-2)(8)=-16

x+6x-16=-2

7x-16=-2

move -16 to the other side

sign changes from -16 to +16

7x-16+16=-2+16

7x= -2+16

7x= 14

divide both sides by 7

7x/7=14/7

x=2

Find y by using the substitution method

y=-3x+8

y=-3(2)+8

-6+8

=2

Jennifer used 0.42 gallons of paint to completely cover a square wall with an area of 168 square feet. Which measurement is clos
Marina86 [1]

Answer:

The answer to this question is: 12.96 ft ≈ 13 ft

Step-by-step explanation:

Data

Area 168 ft²

Length = ?

Volumen = 0.42 gallons

But we do not need the volume of paint because we know that the wall is squared-shape.

Only we need to know the formula to obtain the area of an square.

Formula   area = length²

So            168 = length²

Finally      √168 = length

             length = 12.96 ≈ 13 ft
