Answer:
A) 10x + 8 = 21
B) x = 1.3
Step-by-step explanation:
2(2x + 3) + 2(x + 1) + 4x = 21
4x + 6 + 2x + 2 + 4x = 21
10x + 8 = 21
10x = 13
x = 1.3 cm
Answer:
(-8) + (-8) + (-8) + (-8)
Step-by-step explanation:
Since Yan is descending ; we represent his movement as being negative.
Number of rungs descended before stopping = 4
Number of stops = 8
Given that no extra steps was taken ;
Number of ladder rungs descended :
4 rungs per stop for 8 stops
- 4 * 8 = - 32 rungs
Another way to write the product :
Number of stops added in number of rungs descended :
(-8) + (-8) + (-8) + (-8)
√25 = 5
5 × 5 = 25
She should plant 5 rows with 5 plants each.
