\large{\rm{\underline{\underline{Answer:}}}}

a) <u>n² + 6 </u>

~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.

  • If n = 1, first term = 1² + 6 = 7
  • n = 2, second term = 10
  • n = 3, third temm = 15
  • n = 4, fourth term = 22
  • n = 10, tenth term = 106

b) <u>3n²</u>

  • If n = 1, first term = 3
  • n = 2, second term = 12
  • n = 3, third term = 27
  • n = 4, fourth term = 48
  • n = 10, tenth term = 300

-12 + 9 - (-3) - 11

Remember PEMDAS: This is the order of operation.
P-Paragrahp
E-Exponent
M-Multiply
D-Divide
A-Add
S-Subtract

1st step: PEM
-(-3) is actually -1 * -3 = + 3

-12 + 9 + 3 - 11

2nd step: D is not possible, so we do A.
9 + 3 = 12

3rd Step: Subtract
12 - 12 - 11 = 0 - 11 = -11 CHOICE B.

Which is a factor of 144 − 49x2?<br><br> 12 - 7x2<br> 72 – 7x2<br> 12 – 7x<br> 72 + 7x
Vinil7 [7]

Answer:

(12-7x)

Step-by-step explanation:

144 − 49x²

by observation, we can see that 144 = 12² and 49 = 7²

hence we can rewrite the equation

144 − 49x²

= 12² - 7²x²

= 12² - (7x)²

recall that the expression x² - y² = (x+y)(x-y)

hence,

12² - (7x)²

= (12 + 7x)(12-7x)

(12-7x) appears in the expression above, hence 12 -7x is a factor
