Answer:
The models have tiles corresponding to x+8 and x+1
Step-by-step explanation:
We want to find the model that represents factors of
We split the middle term to get:
We factor by grouping to obtain:
We collect common factors again to get:
The models have tiles corresponding to x+8 and x+1
Answer:
2
Step-by-step explanation:
137,426.9 is 140,000 when rounded to 2 sig figs
Answer:
Step-by-step explanation:
= x - 5 ( x ≥ 3 )
( )² = ( x - 5 )²
x - 3 = x² - 10x + 25
x² - 11x + 28 = 0
(x - 4)(x - 7) = 0
= 7
= 4
Check the answer:
1). x = 7
= 7 - 2
√4 = 2
2 = 2
2). x = 4
= 4 - 5
1 = - 1 (False statement) ⇒ x = 4 is an extraneous solution.
You would use meters to measure.
