Step-by-step explanation:
The side of the square = x + 2, thus area is equal to
(x + 2)² ← expand using FOIL
= x² + 4x + 4
Given area = 7 then
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
Answer:
a) 200 mm^2
b) 500 mm^2
c) 3.75e + 8
d) 6390 cm^2
e) 650 cm^2
f) 20 m/s
Step-by-step explanation:
For a) and b): 1 cm = 10 mm, multiply 20 (and 50) by 10
For c): the formula is to multiply 1e + 8
For d): 1 Liter = 1000 Cubic Centimeters (hopefully that's what you're referring to)
For e): 10 mm = 1 cm, divide by 10
For f): divide the value by 3.6
