Answer:
66

Explanation:
Volume for any prism=base area*height

The base is a triangle and the formula to find the area of a triangle is Area=(base*height)/2. Once we input the values it would look like:

Area=(4*3)/2
A=12/2
A=6

In this case, the height of the prism would be 11. Now we input our values for finding the volume:

Volume for any prism=base area*height
Volume=6*11
Volume=66

I hope this helps! Please comment if you have any questions.

5x-4y-6z = -3<br> X-3y+z=-1<br> -3x-6y+7z=1
PilotLPTM [1.2K]

Answer:

x=-\frac{41}{55},y=\frac{2}{55},z=-\frac{8}{55}

Step-by-step explanation:

5x-4y-6z=-3...............eq(1)\\\\x-3y+z=-1.....................eq(2)\\\\-3x-6y+7z=1.................eq(3)

eq(1)-5\times eq(2)

5x-4y-6z-5(x-3y+z)=-3-5\times (-1)\\\\11y-11z=2\\\\y-z=\frac{2}{11}...................eq(4)

3\times eq(2)+eq(3)

3(x-3y+z)-3x-6y+7z=3\times (-1)+1\\\\-15y+10z=-2\\\\-y+\frac{2}{3}z=-\frac{2}{15}.........eq(5)

eq(4)+eq(5)

y-z-y+\frac{2}{3}z=\frac{2}{11}-\frac{2}{15}\\\\-\frac{1}{3}z=\frac{8}{165}\\\\z=-\frac{8\times 3}{165}\\\\z=-\frac{8}{55}

From eq(4)

y=z+\frac{2}{11}=-\frac{8}{55}+\frac{2}{11}\\\\y=\frac{2}{55}

Substitute the value of y and z in eq(2)

x-3\times \frac{2}{55}-\frac{8}{55}=-1\\\\x-\frac{14}{55}=-1\\\\x=-1+\frac{14}{55}\\\\x=\frac{41}{55}

Ughhhhhhhhh last one
Lubov Fominskaja [6]

Answer:

c) x=13

Step-by-step explanation:

4x + 2 = 90 − 36

Step 1: Simplify both sides of the equation.

4x + 2 = 90 − 36

4x + 2 = 90 + −36

4x + 2 = (90 + −36) (Combine Like Terms)

4x + 2 = 54

4x + 2 = 54

Step 2: Subtract 2 from both sides.

4x + 2 − 2 = 54 − 2

4x = 52

Step 3: Divide both sides by 4.

4x/ 4  =  52/ 4

x=13

if you need a shorter way to get this... is to do what i did and just used MathPapa's algebra calculator and put in "4x + 2 = 90 - 36" cause that's basically what the question is asking you to use... im not saying to do my method... im just saying that's how i got it
