Step-by-step explanation:
The product of the sum of a and b and their difference:
(a + b)(a - b) = a² - b²
Proof:
L = (a + b)(a - b) <em>use FOIL</em>
L = (a)(a) + (a)(-b) + (b)(a) + (b)(-b)
L = a² - ab + ab - b² <em>combine like terms</em>
L = a² - b² + (-ab + ab)
L = a² - b²
R = a² - b²
L = R
Answer:
c.
Step-by-step explanation:
1.25x5=6.25
6.25+1.37=7.62
Answer:
it is half the area of a square of side length 8
Step-by-step explanation:
area of a square = l × b
= 8 × 8
= 64 cm^2
area of a triangle = b × h ÷ 2
= 8 × 8 ÷ 2
= 64 ÷ 2
= 32 cm^2
