Answer:
<h3>h = 5</h3>
Step-by-step explanation:

Answer:
1/6
Step-by-step explanation:
the distributive property one side has to equal the other
The area of a shape is the amount of space it can occupy.
<em>The surface area of the larger prism is 4 times the surface area of the smaller prism.
</em>
<em />
<em />
<em>Let the dimension of one side of the smaller prism be: l and w</em>
<em>Let the dimension of one side of the bigger prism be: L and W</em>
<em />
So, we have:


The area of these corresponding sides are:
---- the first

While, the area of the second is:


The ratio of these two sides are:

<em>This gives</em>

Cancel out common terms

Express as fractions

Also, we have:

This gives

Cross multiply


Hence, option (c) is true

3) x² - 121 = 0
x² = 121
x' = +√121
x' = 11
_______________
x'' = - √121
x'' = -11
Solution ⇒ S{-11 ; 11 } or (x-11)(x+11)
4) 4x² + 144 = 0
4x² = -144
x² = -144 / 4
x² = -36
x = √-36
No solution ⇒ S = ∅
5) z²+10z+21 = 0
Δ = 10² - 4(1)(21)
Δ = 100 - 84
Δ = 16
x' = (-10+4) / 2 = -6/2 = -3
x'' = (-10-4) / 2 = -14/2 = -7
Solution ⇒ S{ -7 ; -3} or (x+3)(x+7)
Sorry I can’t explain this very well but it would be 50 because the rate is 240:10, 240x5= 1,200, so 10x5 would get you the gallons of gasoline she uses.
