Answer:
x = 8√5
Step-by-step explanation:
In the figure attached, there are three right angle triangles.
So, by Pythagoras theorem,
y²+ 4² = z²
y² + 16 = z²------(1)
Similarly x² = 16² + y²--------(2)
and (16 + 4)² = x² + z²
20² = x² + z²-------(3)
Now we put the value of z² from equation 1 to equation 3
20² = x² + y² + 16
x² + y² = 400 - 16
x² + y² = 384
y² = 384 - x²------(4)
Now we put the value of y² from equation 4 to equation 2
x² = 16² + 384 - x²
2x² = 256 + 384
2x² = 640
x² = 320
x = 8√5
Therefore x = 8√5 will be the answer.
4/7 = 12/21
12/21 = x + 3/21
9/21 = x
Hope this helped!!
I’m pretty sure it’s D. Because if you flip the x values then you would just move them over the y axis
Answer:
3/1 is the slope using the point slope formula
Ratio: 4:3
96/4 bird houses shows the number to connect the ratios, you get 24. Then do 24 times 3 ( because of 3 days ) to get 72 days.
Answer: 72 days
