Question

With solution pls I will mark the one who will answer correct and with solution brainliest... and answering incorectly just to gain points will be reported.
Evaluate the each algebraic expression, if a = 3 b = 1 c = 0
1. a + c + c =_______
2. 2a - 2b + 3c = ________
3. a3 – (ab2) + ac = ________
4. ab + 2c = ________
5. 3ab – a2 = ________

Perform the following operations.
1. (5x4 – 3x2 + 4) + (6x3 – 4x2 – 7)
2. (3y5 − 2y + y4 + 2y3 + 5) + (2y5 + 3y3 + 9)
3. Subtract 4x3 – 5x – 8 from 6x2 – 3x + 8
4. (5x3 – 7x2 + 3x – 4) –(8x3 + 2x2 +3x – 7)
5. (9x5 – 6x3 + 7x2) – (7x3 – 6x5 + 2x2)

Answer 1

Answer:

so it is given that a = 3

b = 1

c =0

Step-by-step explanation:

1. a + c + c = 3 + 0 + 0 =3

2 . 2a - 2b + 3c = 2 x 3 - 2 x 1 + 3 x 0

                         = 6-2+0

                         = 4

3. a3 – (ab2) + ac = 3 x 3 - ( 3 x 1 x 2 ) + 3 x 0

                             = 9 - 6 + 0

                             = 3 + 0

                             = 3

4. (ab) + 2c = 3 x 1 + 2 x 0

                  = 3 + 2 x 0

                  = 3 +0

                  = 3

5. 3ab – a2 = (3 x 3 x 1 ) - 1 x 2

                   = 9 - 2

                   = 7

hope that helps 'cause i just did what i want to
