For the first one, its 86 square in, and the second one is 45 square cm.
Answer:
Base area=16
Volume=88/3
Step-by-step explanation:
Took the test
<span>Let x = first number
Let y = second number
x + y = 4
x * y = (-12)
Solve the first equation for x.
x = 4 - y
Now substitute this value of x into the second equation.
(4 - y) * y = (-12)
4y - y² = (-12)
y² - 4y - 12 = 0
(y + 2) * (y - 6) = 0
Now set both polynomials equal to zero
y + 2 = 0
y = -2
y - 6 = 0
y = 6
If you substituted these two values for y into either equation and solve for x, you would get the combination of 6 and -2
Hope I was able to help you! :)

The ratio of the number of children to the number of adults in this group is 2 : 3
<h3>How to determine the ratio?</h3>
The admission is given as:
Children=4
Adult = 6
Express as ratio
Ratio = Children : Adult
This gives
Children : Adult = 4 : 6
Simplify
Children : Adult = 2 : 3
Hence, the ratio of the number of children to the number of adults in this group is 2 : 3
