A:$7.75
B:$8.75
C:$9.50
D:$0.75
Answer:
7+5 first because of pemdas
7+5 = 12
12+4 x 13-2
then 4 x 13
4 times 13 = 52
12+52-2
then add
12+52 = 64
64-2
then subtract
64-2 = 62
Step-by-step explanation:
Pemdas
Answer:
358
Step-by-step explanation:
set this equal to zero.
subtract 100 from 18000
divide by 50
=358
The sum is 4x³ + 3x² + 2x – 6.
Solution:
The correct question is given below.
(4x³ – 2x² + 3x – 1) + (5x² – x – 5). What is the sum?
<u>To find the sum of the polynomial:</u>
Sum of (4x³ – 2x² + 3x – 1) and (5x² – x – 5)
= (4x³ – 2x² + 3x – 1) + (5x² – x – 5)
Remove the parentheses.
= 4x³ – 2x² + 3x – 1 + 5x² – x – 5
Group like terms together.
= 4x³ – 2x² + 5x² + 3x – x – 1 – 5
Add the similar elements. i.e the element with same power.
= 4x³ + 3x² + 2x – 1 – 5
Subtract the constant terms.
= 4x³ + 3x² + 2x – 6
The sum is 4x³ + 3x² + 2x – 6.
