Tamara says she used the GCF to factor the expression 21x + 56xy as 7(3x + 8xy). Is she correct? Explain. 00:00
Yes; 7 is the GCE.
00:00
No; 14 is the GCF
00:00
No; 7x is the GCF.
00:00
No; 7xy is the GCF

77xy

Step-by-step explanation:

if you multiply 7x3x that equals 21x and if you multiply 7x8xy that will equal 56xy now you need to add 21x+56xy that will equal 77xy

a. 3/4 ÷ 1/8 = 6

step-by-step explanation:

in the question, the number line represents 3/4 divided into 6 equal units. each arrow represents a unit and there are a total of six arrows.

the size of each unit is 1/8 as shown.

showing that 1/8 divides 3/4 into 6 divisions:

3/4 ÷ 1/8

= 3/4 x 8/1

= 3/1 x 8/4

= 3 x 2

= 6

hence, the number line represents six divisions given by 3/4 ÷ 1/8.

i just took the test, the correct answer is .. 31.5 in.
