First, find the missing leg of ΔBCD (line BD). Using the Pythagorean Theorem, subtract (5^2)-(3^2) [25-9], and you get 16. Find the square root of 16, and you get <em>4</em> for line BD. Now, you can find AB. Add (7^2)+(4^2) [49+16], and you get 65. Now, since 65 isn't a perfect root, just use √(65)
Answer: Line AB equals √(65).
Answer:
130lbs
Step-by-step explanation:
1) 52 ÷ 4≈ 13
2) 13×10=130
The absolute value of -5 is 5.
Knowing this we know that |5| -|-5| is 5 - 5
5 - 5 = 0
Answer:
y = -3x + 41
Step-by-step explanation:
All you need to do is expand everything and solve for y.
y- 5 = -3(x - 12)
y - 5 = -3x + 36
y = -3x + 41
I hope this helped!
Answer:
or
27 
Step-by-step explanation:
Any regular whole number (37 for example) is over one so it would look like 
. Multiplying fractions involve just multiplying the numerators and denominators together, therefore it would look like ×. Now just multiply the top and bottom numbers together and this will leave you with . But if you'd like to make it into a mixed number (more simplified version of ) then you would get 27 .
