GCF is the Greatest Common Factor. It would be the largest number that can divide evenly into all the numbers you need to find the GCF in.

exapmple GCF for 12 and 16

12: 1, 2, 3, 4, 6, 12

16: 1, 2, 4, 8, 16

the largest common number is 4, so 4 is the GCF of 12 & 16


LCM = Least Common Multiple is the smallest number ( other than zero) that is a multiple of both

LCM of 3 and 5

3: 3, 6, 9, 12, 15, 18
5: 5, 10, 15, 20
 the first common number is 15, so this is the LCM of 3 & 5

Help me please <br> !!!!!!!!!!!!
Tpy6a [65]

Answer:

40

Step-by-step explanation:

Angle Formed by Tangent and Secant = 1/2 (DIFFERENCE of Intercepted Arcs)

< WVT = 1/2 ( WT - UW)

3x+4    = 1/2 (( 14x +7) - (7x+11))

Distribute

3x+4    = 1/2 ( 14x +7 - 7x-11)

Combine like terms

3x+4    = 1/2 ( 7x -4 )

Multiply each side by 2

6x +8 = 7x-4

Subtract 6x from each side

+8 = x-4

Add 4 to each side

12 =x

WVT = 3x+4

        = 3*12 +4

       = 36+4

       = 40

If the perimeter of a rectangular picture frame must be less than 200 in., and the width is 36 in., what must the height h of th
Zigmanuir [339]
The perimeter is 2 width + 2 length. So 200 = 2(36) + 2 length and that simplies to 200 = 72 + 2 length. Now we have to subtract 72 from both sides to get the 2 lengths alone. So 128 = 2 length. Finally, we divide both sides by 2 to get the length alone. 64 = length. Now since the perimeter has to be less than 200 inches than the length can be any number less than 64. Hope this helps and if so please leave a good rating and thanks and maybe even brainliest answer. Thank you I really appreciate it. Have a nice day!

Tcecarenko [31]
Answer=Carlos

If Jackie has 10 groups, with 3 in each groups, she has 30 total pennies.

10*3=30 pennies

If Carlos has 5 groups with 100 in each group, then Carlos has 500 pennies.

5*100=500 pennies

500 pennies is more than 30 pennies, so Carlos has more pennies
