Answer:
No they are not equal;
a = -13
Step-by-step explanation:
Here, we want to find the value of a
We are gong to use the ratio given
That will be;
a + 3/ 7 + a = 4/5
5(a + 3) = 4(7 + a)
15 + 3a = 28 + 4a
4a - 3a = 15-28
a = -13
Set up variables:
l = length
w = width
p = perimeter
A = area
Relations:
A = lw
32 = 2l + 2w (perimeter)
l = 3w
Find the missing info:
32 = 2(3w) + 2w (solve for w)
32 = 6w + 2w = 8w
w = 32/8 = 4
If width equals to 4, then length would be 4 * 3, 12.
Area = 12 * 4 = 48
Answer:
exponential growth
Step-by-step explanation:
Question 4 -
Mean: 20
Median: 22
Question 5 -
The median describes the data the best, because when calculating the mean, you include the outlier of 7.
