Answer:
B
Step-by-step explanation:
Using the pythagorean triples: 3,4,5 you can determine the third side.
Using a right triangle you have a hypotenuse of 5, the height of the triangle would be 4, so then the base would be 3 but you have two right triangles together so you have to double it which equals 6.
Answer:
32
Step-by-step explanation:
18 : 6 = 3
therefore, x : 3 has to equal 3.
X : 3 = 3
X = 3 × 3
X = 9
To verify:
18 : 6 = 9 : 3
3 = 3
It's true that X = 9, so now just replace the X with 9 in the next equation
5 + 3(9) = 32
