Answer: 591
Step-by-step explanation:
12 x 13= 156
12 x 5= 60 x 2= 120
12 x 5= 60/2= 30 x2= 60
5 x 12= 60
13 x 15= 195
195 + 60 + 60 + 120 + 156= 591
Answer:
1=18
2=20
3=32
4=54
Step-by-step explanation:
Multiply numerator and denominator by the conjugate of the denominator
Denominator: -10 + 8i
Conjugate of the denominator: -10 - 8i
Operation:
[9 +7i] / [-10 + 8i] * [-10 -8i] / [-10 - 8i] = [-90 - 72i - 70i +56] / [100 + 64] =
[-34 -142i] / 164 = [-17 -71i] / 82
Answer:
280
Step-by-step explanation:
(17 x 24) - (8 x 16)
(408) - (128)
408 - 128 = 280
Answer: 280
Answer:
6 1/4
Step-by-step explanation:
Add up the fabric that she has
3 1/2 + 6 3/4
Get a common denominator
3 2/4 + 6 3/4
9 5/4
9 4/4 + 1/4
10 1/4
Subtract this from the fabric that she needs
16 1/2 - 10 1/4
Get a common denominator
16 2/4 - 10 1/4
6 1/4
