Answer:
59
Step-by-step explanation:
You will multiple them all 5*5=25,4*4=16,6*3=18 then add 25+16+18=59
To create this pattern, you can start with the number zero and apply this math. 0 x 2 +1 = 1. The next number would be found by taking 1 x 2 + 1=3. After that 3 x 2 + 1 = 7. The next number in the pattern would be found by taking 7 x 2 +1. Essentially, you are just taking the answer you just got and doubling it and then adding 1. Here is the pattern that would be created beginning with 0. 0, 1, 3, 7, 15, 31, 63, etc...
Answer:

Step-by-step explanation:
F(x) = x² + 4x - 1
f(x) = x² + 4x + 4 - 4 - 1
f(x) = (x + 2)² - 5
Answer:
x = 36 and y = 72
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an external angle to the triangle on the right, thus
y = 2x
The sum of the 3 angles in a triangle = 180
Consider the triangle on the left. then
x + 2y = 180 ← substitute y = 2x
x + 4x = 180
5x = 180 ( divide both sides by 5 )
x = 36 and y = 2x = 2 × 36 = 72
