The following are the answers for these:

(5x + 3)(5x – 3) ----> Difference of squares

(7x + 4)(7x + 4) ----> Perfect square trinomial

(2x + 1)(x + 2) ----> Neither

(4x – 6)(x + 8) ----> Neither

(x – 9)(x – 9)-----> Perfect square trinomial

(–3x – 6)(–3x + 6) -----> Difference of squares.

The easiest way to tell these is that if the parenthesis are exactly the same it will be a perfect square trinomial. If the parenthesis are the same except for the sign in between the terms, it is a difference of square. If it has neither of these, then it is neither.

Which is equal to 2.6 x 2.6 x 2.6 × 2.6?<br> 42.6<br> (2.6)4<br> 4 x 2.6<br> 26²
tester [92]
(2.6)^4 is the answer.


We know that multiplying is the act of adding a number to itself a series of times. However, this is multiplying said number by itself, meaning that our answer is an exponent.

Because our number is 2.6 and we’re multiplying it 4 times, our answer is (2.6)^4

Basher collected 4 1/3 basket of peaches and Orchard if each basket holds 21
miv72 [106K]
To do this you times 3 by 4 and add it on to the numerator of the fraction, to turn it into a top heavy fraction:
3*4 = 12
1+12/3 = 13/3

Then you multiply the numerator by 21 to work out what 21 times the fraction is:
13*21/3 = 273/3

Then you can divide 273 by 3 to get the final answer:
273/3 = 91

He will have 91 peaches overall.
Hope this helps! :)
