Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the 2 other sides, that is
x² + 6² = 17²
x² + 36 = 289 ( subtract 36 from both sides )
x² = 253 ( take the square root of both sides )
x =
→ C
45/3=15 45-15=30 30/5=6 3x6=18 30-18=12 the answer is 12
Answer:
9
Step-by-step explanation:
18÷3=6
6×2=12
12+4=16
16÷2=8
8+1=9
X
X+2
X+4
Those are 3 consecutive odd integers
Step 1. Add 72 to both sides
5y = 7 + 5x + 72
Step 2. Simplify 7 + 5x + 72 to 5x + 79
5y = 5x + 79
Step 3. Divide both sides by 5
y = 5x + 79/5
