Answer:
Step-by-step explanation:
Using FOIL (First, outer, inner, last)
First, we multiply 3x and x to get 
(First)
We then multiply 3x and 1 to get 
(outer)
Then 4 and x to get 
(Inner)
Then multiply 1 and 4 to get 
(last)
Since the quadratics are all positive, we add all the terms together to get:
. Since 3x and 4x are like terms, we add them together and simplify to get:
And since we can't simplify any further, that's our answer!
Hope this helps :D
Answer: 3/4
Step-by-step explanation: 8/5×15/32 equals 3/4
8/5 * 15/32= Now you must use inverse operations five goes into 15 3Times 8goes into 32 4 times Crossout eight and five cross out 15 and 30 to 3×1 = 3 and 4×1 = 4 so 8/5×15/32 equals 3/4
Answer:
the person earned one summer = $3,600
We have to show the amount in fraction that Paula spent during the following semester,
they spent for tuition = $2,500 = × 100
=0.6944 × 100
= 69.44%
they spent for rent = $650 = × 100
= 0.1806 × 100
= 18.06%
they spent for food = $430 = × 100
=0.1194 × 100
= 11.94%
they Spent in tuition, rent and food = 2,500 + 650 + 430 = $3580
Now they spent in miscellaneous expenses = 3600 - 3580 = $20.00 × 100
= 0.056 × 100
= 0.56%
