Harish has ruppees 80. he wants to buy toffees,8/5 ruppees. how many toffees can he buy?

1 answer:

5 0

U set up an equation: 80 x 8/5
Then u can cross multiply bc 5 goes into 80
It goes into 80 exactly 16 times
So new equation: 16 x 8
Multiply that out and u get 128

(3x-4y)^2-(3x-4y)(3x+4y)

zheka24 [161]

Answer:

$-24xy + 32y^2$

Step-by-step explanation:

Hello!

We can use the special binomial product formulas:

$(a + b)^2 = a^2 + 2ab + b^2$
$(a + b)(a - b) = a^2 - b^2$

<h3>Simplify</h3>

$(3x - 4y)^2 - (3x - 4y)(3x + 4y)$
$(9x^2-24xy+16y^2) - (9x^2 - 16y^2)$
$9x^2 - 9x^2 - 24xy + 16y^2 + 16y^2$
$-24xy + 32y^2$

The simplified form is $-24xy + 32y^2$
