Answer:
37
Step-by-step explanation:
To find the side length in the middle is 12. This is because A(12) squared + B(5) squared = C(13) squared.
Now that we know the side length, we can find x. A(35) squared + B(12) squared = C(x) squared.
35*35=1225.
12*12=144.
1225+144=1369
The root of 1369 is 37, so the value of x is 37.
Answer:
Can you post a picture or something?
Step-by-step explanation:
Step 1:
x² + 4x = 192
Step 2:
Take x common:
x ( x + 4) = 192
Length is x and width is x+4
Step 3:
x² + 4x - 192 = 0
Step 4:
x² + 16x - 12x - 192 = 0
x(x+16) - 12(x+16) = 0
(x-12)(x+16) = 0
⇒ x=12, x=-16
Because the length can't be -16, the length is 12.
Answer:
300 bears left
Step-by-step explanation:
400 x 0.05 is 20. 20 is how many will be gone in one year. 20 x 5 is 100. 100 is how many will be gone in 5 years.
400 - 100 is 300. Hope this helps, please tell me if i am wrong
