Answer:
A - 5 square root of 3
Step-by-step explanation:
Take one of the triangles and use the pythagorean theorem. A^2 + B^2 = C^2
Hence,
5^2 + x^2 = 10^2
25 +x^2 = 100
25 +x^2 -25 = 100-25
x^2 = 75
Take the square root of both sides. . .
x = 5 square root of 3
Answer:
x = 16.
Step-by-step explanation:
x - 4 = 3/4 x
x - 3/4 x = 4
1/4 x= 4
x = 4*4
x = 16 (answer).
Answer:
3 times a number (3x)

Answer:
-36
Step-by-step explanation:
Answer:
b=4 makes the equation a perfect square.
Step-by-step explanation:
As long as you factorize out the equation, you'll get a result of (x+2)^2. This multiplied using foil gives you, x^2 + 2x + 4. Making it a perfect square. You could also have -2 = b which makes a perfect square, but that's not in the options.
