Answer:
A, B, and E
Step-by-step explanation:
A. The terms 4x³ and 8x have a common factor (it is 4x)
B. The terms 4x3 and – 6x2 have a common factor (it is 2x²)
E. The polynomial can be grouped in different ways to factor by grouping.
( (4x³ - 6x²) + (8x - 12) ⇒ 2x²(2x-3) + 4(2x-3) ⇒ (2x²+4)(2x-3) )
Answer:
ABD = 40, CD = 143, X = 43.5, AB = 140, BC = 126
Sorry I'm in a hurry right now so I can't give explanations but I hope this helps!
Hi there!
To find the unknown addend, we can just subtract:
1 - 2/6 = 4/6
4/6 = 2/3
Hope this helps!
Step-by-step explanation:
one could be that all the angles add up to 180
180-71= 109
∠DBC and ∠ABC must add up to 109 degrees
For No. 13 you need to calculate the distance each girl travels and compare to see whose distance is greater. The formula for distance is rate x time or d=rt. The rate is just how fast they consistently go.
Mia
d = r x t
d = 14 x 3/2
d = 21 miles
Chloe
d = r x t
d = 35 x 3/4 (btw 3/4 is just 45/60 simplified)
d = 105/4 = 26 1/4 miles
Final Answer: Chloe traveled further
For No. 14 we will recalculate Mia's distance but replace 1/5 hours with 2 hours because it says she will bike 30 minutes after Chloe had stopped. Afterwards we will compare Mia's new distance with Chloe's old distance.
Mia
d = r x t
d = 14 x 2
d = 28 miles
Final Answer: Yes Mia would be able to catch up to Chloe, and even surpass her in 30 minutes if Chloe stopped.
