Answer:
a = 12cm
Third option
Step-by-step explanation:
Use the pythagorean theorem because this is a right triangle and you are looking for a missing side.
The formula is:
a² + b² = c², where "a" and "b" are sides, but "c" is the hypotenuse (longest side).
We know the hypotenuse and one other side.
Substitute side "b" and "c".
a² + 5² = 13²
a² + 25 = 169 Isolate "a"
a² = 169 - 25 Subtract 25 from both sides
a² = 144 Find the square root of both sides
a = √144
a = 12
The mssing side, "a", is 12 cm long.
Answer:
x(x - 1 ) = 0
Step-by-step explanation:
x^2 - x + 3 = 3
subtract 3 from each side:
x^2 - x = 0
x(x - 1 ) = 0
Answer: 16 cans
Step-by-step explanation: Think of it being in batches, you can make 4 batches of green paint with 24 cans of yellow paint, so you would need 16 cans of blue paint to get the same shade of green if you mix the 24 cans and 16 can's together at once
Answer:
B
Step-by-step explanation:
1/2x - 2 > 0
collect like terms
1/2x > 0 + 2
1/2x > 2
Divide both sides by 1/2
x > 2 divided by 1/2
inverse of 1/2 is 2/1
x > 2 times 2/1
x > 4
I am pretty sure that B is the answer
