Simplify: 3 · 32 + 8 ÷ 2 − (4 + 3)
Law Incorporation [45]

Answer: 93

Step-by-step explanation:

To solve this we need to follow BIDMAS.

The order of calculations is brackets, division, then multiplication, then addition, then subtraction.

1) (4 + 3) = 7

2) Division: 8 / 2 = 4

3) Multiplication: 3 * 32 = 96

This leaves us with:

96 + 4 - 7

This equals 93.

Solve for the distance between (522, 1322) and (9000, -1337) to the third decimal.
SSSSS [86.1K]
A pair of coordinate always in a form (x, y)
Let (522, 1322) be (x₁, y₁) and (9000, -1337) be (x₂, y₂)

The distance between two coordinates is given by
Distance = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}
Distance = \sqrt{(522-9000)^2+(1322--1337)^2}
Distance = \sqrt{(-8478)^2+(2659)^2}
Distance = \sqrt{78946765}
Distance = 8885.200 (rounded to three decimal place)
