Answer:
81y^4 - 16x^2, difference of squares.
Step-by-step explanation:
So we need to expand the following product:
(9y2-4x)(9y2+4x) = 9y2*9y2 + 4x*9y2 - 4x*9y2 -4x*4x = 81y^4 - 16x^2
And this type of product is the difference of squares.
Answer:
the given equation is arranged as follow
Step-by-step explanation:
<u>2x²+x-6 </u> × <u>x²+5x+6</u>
x²-x-6 4x²-9
<u>(x+2)(2x-3) </u> × <u> (x+3)(x+2)</u>
(x-3) (x+2) (2x+3) (2x-3)
<u>(x+2)(x+3)</u>
(2x+3)(x-3)
option b
Answer:
11 33/35
Step-by-step explanation:
5 3/7 = 5 × 7/7 + 3/7 = 35 + 37 = 38/7
38/7 ÷ 5/11 = 38/7 × 11/5 = 38 × 11/7 × 5 = 418/35
418/35 = 11 33/35
Hope this helps!
