A = 12.96148 b = 11
a^2 + b^2 = c^2
(12.96148)^2 + (11)^2 = c^2
168 + 121 = c^2
289 = c^2
c = sqrt(289)
c = 17 I did a little bit of rounding to get this, but I'm sure it is close enough.
I just encountered this question. Here's my answer:
Given:
3 kids
product of their ages is 72.
Youngest child.
The youngest child means that all three kids have different ages.
We need to factor 72. Let us use prime factorization.
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
1 x 2 x 2 x 2 x 3 x 3 = 72
Based on the factors we can assume the following ages:
2 x 4 x 9 = 72
3 x 4 x 6 = 72
1 x 8 x 9 = 72 I prefer this age combination.
1 x 3 x 24 = 72
<span>1 x 4 x 18 = 72</span>
You can add up all the equal terms:
So for x: 6x-4x = 2x
For y: 2y
For the numbers: 3+7=10
Hi there!

Step-by-step explanation:
We find the equation of the solid blue line:
The line decreases by 1 unit for every 3 units across.
=> Slope of line = -1/3.
Also the y-intercept is 1.
=> Line equation: y = -1/3 x + 1.
We see that the graph below this line is shaded.
Therefore all y-values below or on the line are represented by the graph.
=> y <= -1/3 x + 1.
The answer is y <= -1/3 x + 1.
