Answer:
t1= -4
Given that result we must now find "n"
Answer:
8 inches.
Step-by-step explanation:
From the statement we have that they first made two identical square pyramids, each with a base area of 100 square inches.
Ab = s ^ 2 = 100
Therefore each side would be:
s = (100) ^ (1/2)
s = 10
So, side of the square base = 10 inches
Then they tell us that they glued the bases of the pyramids together to form the precious stone. The surface area of the gemstone is 520 square inches, so for a single pyramid it would be:
Ap = 520/2 = 260
For an area of the square pyramid we have the following equation:
Ap = 2 * x * s + s ^ 2
Where x is the height of each triangular surface and s is the side of the square base
Replacing we have:
260 = 2 * x * 10 + 10 ^ 2
20 * x + 100 = 260
20 * x = 160
x = 160/20
x = 8
Therefore, the value of x is 8 inches.

Answer:
B
Step-by-step explanation:
if you look at it, it increases up to -4, and then it also decreases at -4 because it's the same line. I'm really bad at explaining so I'm sorry if this doesn't make sense.
24 flowers
First we have to add the number of red flowers he has to the number of white flowers he has. This gets us the total number of flowers he has to plant. 40 plus 80 gets us 120 total flowers. Next we must divide this total number of flowers by the number of beds to get how many flowers will be planted in each bed. 120 divided by 5 is 24 flowers per bed.
