Which property is shown? –7 + 24 = 24 + (–7) A. associative property B. distributive property C. opposite of a sum property D. commutative property

Answers

B Commutative Property

This is the commutative property. This is because the commutative property just moves stuff around for example a+b = b+a, is the commutative property. The associative property is a+(b+c) = (a+b)+c, the distributive property is a(b+c) = ab+ac, and the opposite of a sum property is -(a+b) = (-a)+(-b).

Kiwi orders programs for the school play. Each program measures 8 inches long by 5 inches wide by 1/8 inches thick. The programs arrive in one box that is 8 inches long by 15 inches wide by 1 foot deep. What is the greatest number of programs that Kiwi could have ordered?

Answers

The box is 15 inches wide, so only 3 books can fit side by side. Since the box is 1 foot deep and each program is 1/8 of an inch then 1/8 of a inch is .125 inches then you would divide 1 foot( 12 inches ) by 1/8 (.125 inches) This gives you 96 programs in one row. Since there are 3 rows then we would multiply 96 by 3 which gives 288 programs.

Isiah determined that 5a2 is the GCF of the polynomiala3 – 25a2b5 – 35b4. Is he correct? Explain.

Answers

ok, easy way is that we divide each term by the GCF and if it doesn't divide evenly, then it is not valid

first one
5a^2 divide by a^3
we see that we cannot since the power is higher and there is no 5 so it is not the GCF
