Question

Evaluate each expression if d = 8, e=3,f=4, and g=-1. (13)

1. 2(d+9
2. D/4
3.ef/4
4.4f+d
5.5d-25/5
6.d2+7
7. D-4/2
8. 10(e+7)
9.2g/2

Answer 1

1. 2(d+9) = 34, 2. d/4 = 2, 3. ef/4 = 3, 4. 4f+d = 24, 5. 5d-25/5 = 35, 6. d^2+7 = 71, 7. d-4/2 = 6, 8. 10(e+7) = 100, 9. 2g/2 = -1

Step-by-step explanation:

1. 2(d+9) = 2(8+9) = 2(17) = 34
2. d/4 = 8/4 = 2
3. ef/4 = 3*4/4 = 3
4. 4f+d = 4*4+8 = 16+8 = 24
5. 5d-25/5 = 5*8-25/5 = 40-5 = 35
6. d^2+7 = 8^2+7 = 64+7 = 71
7. d-4/2 = 8-4/2 = 8-2 = 6
8. 10(e+7) = 10(3+7) = 10*10 = 100
9. 2g/2 = 2*(-1)/2 = -1
