Answer:
32
Step-by-step explanation:
since the number of toothpicks are going up by 2 each time, the 15th figure will have 32 toothpicks
We have an equation: 13/?= 26/100
Cross multiply:
26*?= 13*100
⇒ ?= 13*100/26= 50
13 is 26% of 50~
(x+2) - (x-2) = 5. (x-2) (x+2) 6. (x+2)² - (x² - 2)² = 5. (x+2) (x-2) 6. (x² + 4x+4) - (x² - 4x + 4) = 5. x² - 4 6. (x² + 4x + 4 - x² + 4x - 4) = 5. x² - 4 6. 8x = 5.
