then
Answer:
x = 7
Step-by-step explanation:
2x + 1 = -3x + 36
2x + 3x + 1 = -3x + 3x +36
5x + 1 = 36
5x + 1 - 1 = 36 - 1
5x = 35
5x/5 = 35/5
x = 7
Answer:
1044 cm²
Step-by-step explanation:
Split the shape up into two
Area of shape A:
Area = length × width
To calculate the width = 46 - 21 = 25 cm
Area = 30 cm × 25 cm = 750cm²
Area of shape B
Area = length × width
Area = 14 cm × 21 cm = 294 cm²
Add up both of the areas:
750 cm² + 294 cm² = 1044 cm²
