Answer:
11 minutes
Step-by-step explanation:
Because she types only 140 words in 4 minutes so if you add
140+140=280
if you divide
140/4 you get 35
so every minute she types in 35 words. So multiply
11 times 35 and you exactly get 385.
11 min
140 ÷ 4
= 35 which is the amount of words that she types in 1 min.
385 ÷ 35
= 11
so it will take Jenna <u>11 min</u> to type 385 words.
6v(2v+3)2)7（-5v-8）
6v+2v-5v+3+2-8
3v-3
-A+B
if what you mean is what a negative expression would be as a+b the answer would be negative A+B
