Answer:
P = 33z + 3
Step-by-step explanation:
To find the perimeter (P) sum the 4 sides
P = 8z - 3 + 10z - 3 + 6z - 1 + 9z + 10 ← collect like terms
= (8z + 10z + 6z + 9z ) + (- 3 - 3 - 1 + 10)
= 33z + 3
Answer:
Just go pack a bowl
Step-by-step explanation:
Answer:
(3x + 4)(9x² - 12x + 16
Step-by-step explanation:
27x³ + 64 ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
27x³ + 64
= (3x)³ + 4³
= (3x + 4)(9x² - 12x + 16)
90 different ways.
There are 10 ways to choose the first student that goes first, leaving 9 different ways a second student can be chosen. Using combinations, you multiply 10 by 9 to get a total of 90 different combinations, or ways students can be chosen to go first or second.
