2 equations, 2 unknowns. Call height H and base B.
From the first sentence:
HB = 216
From the second sentence:
H = ⅔ B
Plug the second into the first and solve for B:
(⅔ B)B = 216
B^2 = 324
B = 18
Plug that back into either of the original 2 equations and solve for H:
H(18) = 216
H = 12
When the radicals of the quadratic equation (also known as the discriminant) is a positive number that is not a perfect square, the equation has 2 irrational roots
5. 623. Just split the shape into two. then find the area of two figures that you created. Then add.
6. V = 138.125. Just multiply all the numbers together for this problem.
7. SA = 392. Use the formula <span>2(lw + lh + wh). </span>
A bar graph allows you to see each individual data bar, and i'm assuming a "wide range of numbers" which can be done by counting in a pattern (ex: by 5's, by 10's, etc.)
