Answer:
(b) (x -10)(x +10)
Step-by-step explanation:
The factorization of the difference of squares is a special form:
a² -b² = (a -b)(a +b)
<h3>Application</h3>
Your expression is recognizable as the difference of squares:
x² -100 = x -10²
Using the above form, the factorization is ...
= (x -10)(x +10) . . . . . . . . matches the second choice
Answer:
B
Step-by-step explanation:
Multiply through by x+5
2(x + 1) = x + 5 - 1 Combine like terms
2x + 2 = x + 4 Subtract 2 from both sides.
2x = x + 4 - 2
2x = x + 2 Subtract x from both sides.
2x - x = 2 Combine
x = 2
B
Answer:
Case1:
Men : 30
Work : 1
Time (day×hr): 56×6 = 336 hr.
Case2:
Men : let it be m men.
Work: 1
Time: 45×7 = 315 hr.
Work being constant in both cases, men and time are in inverse proportion i.e, more men take less time.
Product of men and time is constant in both cases.
Therefore, 30×336=m×315
Or, 30×336/315 = m
Or, m = 32.
Hence, required number of men is 32.
Step-by-step explanation:
The answer is 88 because if you add 5+3 and then multiply by 11, you would equal out to 88 dogs and cats
