Answer:
10,404/334,084
Step-by-step explanation:
Given the polynomial
289r^2 - 102r + c
We are to find the value of c that will make it a perfect square
Divide through by 289
289r²/289 - 102r/289 + c/289
Half of the coefficient of r is 1/2(102/289)
Half of the coefficient of r = 102/578
Square the result
r² = (102/578)²
r² = 10,404/334,084
Hence the required constant is 10,404/334,084
Answer:
A. 176
Step-by-step explanation: First, to find the surface area to each triangle, you multiply the base times the height by 1/2. It is 28 for each triangle. Multiply that by 4, and you get 112. Then, the surface area of the square on bottom is 64. When added together, you get 176. No rounding needed. Hope it helped and is correct!
Answer: 8a
Step-by-step explanation:
3a + 5a
8a
The level of each growth factor is an illustration of a combination
There are 90 ways of combining one level from each growth factors
<h3>How to determine the
number of combinations?</h3>
From the complete question (see attachment), we have the number of levels in each growth factor is:
Lighting = 3
Age = 5
Temperature = 2
Humidity = 3
So, the number of combination (n) is:
n = 3 * 5 * 2 * 3
n = 90
Hence, there are 90 ways of combining one level from each growth factor.

It’s $11 you just divide 55 by 5 to get that.
