Area = (base)*(height)
15 = (x+7)(x-7)
(x+7)(x-7) = 15
x^2 - 49 = 15
x^2 - 49+49 = 15+49
x^2 = 64
sqrt(x^2) = sqrt(64)
x = 8 ... note that x can't be negative
If x = 8, then the base is...
x+7 = 8+7 = 15
Therefore the base is 15 units.
(the height is x-7 = 8-7 = 1 unit)
Answer: 16 flowers per tree, 352 flowers on 22 trees.
Step-by-step explanation:
115 flowers/ 7 trees= 16.4 flowers per tree
Since you can't have partial flowers, round down to 16 flowers per tree.
16 flowers per tree * 22 trees=352 flowers
Answer:
Part A: yes, this does represent a linear function. For Part B, an example of a linear function would be y=2x. A non-linear function might be y=2^x.
Step-by-step explanation:
For part A, you can see that the function is linear if you plot the points on a coordinate grid. If you click the file, you can see the function plotted.
