<u>Simplify:</u>
- √5(√8 + √18) =
- √5*8 + √5*18 =
- √40 + √90 =
- √4*10 + √9*10 =
- 2√10 + 3√10 =
- (2 + 3)√10 =
- 5√10
<u>The value of a:</u>
Answer:
7
Step-by-step explanation:
Let the height of pyramid be h
v= 224
w= 8
l= 12
224=1/3(12)(8)(h)
224=32h
h=224/32
h=7
Answer:
Step-by-step explanation:
3x+2y=7
Simplifying
3x + 2y = 7
Solving
3x + 2y = 7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
3x + 2y + -2y = 7 + -2y
Combine like terms: 2y + -2y = 0
3x + 0 = 7 + -2y
3x = 7 + -2y
Divide each side by '3'.
x = 2.333333333 + -0.6666666667y
Simplifying
x = 2.333333333 + -0.6666666667y
