The base is a square, so the area of the square is (10 cm)² = 100 cm²
To find the area of each triangle use the formula
base • height
10 cm • 9 cm = 90 cm²
now multiply by the number of triangles
90 cm • 4 = 360 cm²
Add the area of the square:
100 cm² + 360 cm² = 460 cm²
I hope it's correct
4x^2-9
(2x+3)(2x-3)
To verify use distributed
2x(2x) +2x(-3)+3(2x)+3(-3)
4x^2-6x+6x-9
4x^2+0-9
4x^2-9
Dunno the question... But I sure hope if you jump out of a plane the parachute is ALREADY inspected :d
Answer:
19
Step-by-step explanation:
The additive inverse of a number is otherwise known as its opposite.
The additive inverse of 15 is -15.
The additive inverse of -27 is 27.
The additive inverse of 0 is 0 itself!
a + (-a) = 0
A number plus its additive inverse equals zero!
