Algebraic expression: 100 = 25 + n
Answer: n = 75
Problem
Mrs. Taylor handed out 75 sheets of paper to each student in her class. If she has 32 students, how many total sheets of paper did she hand out?
Result
2,400 sheets of paper
Solution
We can solve this using multiplication.
75 · 32 = 2,400
Answer:
(8x - 5y)(8x + 5y)
Step-by-step explanation:
To factor the expression, use the difference of squares pattern. A difference of squares is subtraction between two perfect squares and factors as a² - b² = (a-b)(a+b).
The expression has the perfect squares 64x² and 25y². Take the square root of each. The factors become (8x - 5y)(8x + 5y).
1.SA=10e^2
rectacgular prism=2e*e*e
cube=e*e*e
the length given is 2e=5
so
SA=5e^2
SA=125cm2
