If you don't understand I can send you a picture of the problem. :)

Answers

Answer 1
Answer: 25 a² + 20 ab +  4 b²

for formula a^x+bx^ky^k+cy ^(2k ) find  u,v such that: u.v = a

and u+v = b  then  group according to (ax ^(2k) +ux^ky^k)+(vx^ky^k+cy ^(2k) )

= (25a^2+10ab)+(10ab+4b^2)

factor out 5a from : 25a^2+10ab : 5a(2b+5a)

factor out 2b from : 10ab+4b^2: 2b(2b+5a)

= 5a(2b+5a) + 2b(2b+5a)

factor out : (5a+2b)

= (5a+2b)(5a+2b)

Refine:

(2b+5a)^2

hope this helps!.

What does rounding to the nearest ten square feet mean?

Answers

Round to the nearest tens place.

Final answer:

Rounding to the nearest ten square feet means finding the closest multiple of ten to a given area in square feet.

Explanation:

Rounding to the nearest ten square feet means finding the closest multiple of ten to a given area in square feet. This is done by looking at the tens digit of the number. If the tens digit is 5 or greater, you round up to the next multiple of ten. If the tens digit is less than 5, you round down to the previous multiple of ten. For example, if you have an area of 67 square feet, rounding to the nearest ten square feet would give you 70 square feet.

What is the exact area of a circle whose diameter is 24 cm

Answers

The area formula of a circle is π×r^(2) pi is 3.14 and r is the radius.  The question gives you the diameter.  To find the radius with a given diameter, divide the diameter by 2.  24÷2=12.  The radius is 12.  Now we can multiply 3.14×12^(2) do the exponents first.  12×12=144.  Now multiply that by pi. 144×3.14=452.16
