= 16 + 49 - 3(11) - 4(10)
= 16 + 49 - 33 - 40
= -8
9.99*4=39.96
39.96*.20=7.992 39.96-7.992=31.968
31.968*.0675=2.1578 31.968+2.1578=
$34.13
You use long division to divide decimals
594 divides by 34 equals 17.47
Answer:
B. 21.2
Step-by-step explanation:
Perimeter of ∆ABC = AB + BC + AC
A(-4, 1)
B(-2, 3)
C(3, -4)
✔️Distance between A(-4, 1) and B(-2, 3):




AB = 4 units
✔️Distance between B(-2, 3) and C(3, -4):




BC = 8.6 units (nearest tenth)
✔️Distance between A(-4, 1) and C(3, -4):




AC = 8.6 units (nearest tenth)
Perimeter of ∆ABC = 4 + 8.6 + 8.6 = 21.2 units
