D. 4(x+5)(x-5)
you have to divide the first number out of both terms, then you have the answer. hope this helps
139 = x + (2x + 10)
139 = 3x + 10
129 = 3x
/3 /3
43 = x
Therefore
Question 1)
Gwen has already burned 100 calories when Tristan and Keith started, and he continues to burn 10 calories per minute. The equation for Gwen is
y = 100 + 10x
Question 2)
`Tristan is burning 125 calories every 10 minutes. His burning calories rate is 12.5 calories per minute. The equation for Tristan is
y = 12.5x
Question 3)
Keith is burning 300 calories in 30 minutes. His rate per minute is 10 calories per minute. The equation for Keith is
y = 10x
Divide 5 by 3, he can write 1.66 pages an hour
1.66x8=13.33
Your answer would be 13
3272 I 2
1636 I 2
818 I 2
409 I 409 so bc. 409 is a prime number has factors of 409 and 1
1 I
so the expanded form of 3272 will be 2^3 *409
hope helped
