3 0

Answer:

D) 4^-2

Step-by-step explanation:

Given: 4^4*4^-7*4

If the base is the same, we can add the powers.

a^m * a^n = a^(m + n)

4^4*4^-7*4 = 4^(4 - 7 + 1)

= 4^(5 - 7)

= 4^-2

Answer: D) 4^-2

Hope this will helpful.

Thank you.

6x + 3y = 33 4x + y = 15 A. x = 2, y = 7 B. x = -13, y = 7 C. x = - 2 3 , y = 12 2 3 D. x = 5, y = 1
klio [65]

6x+3y=33..........(1)

4x+y=15

y=15-4x.........(2)

substitute value of y from (2) in (1)

6x+3(15-4x)=33

distribute 3 over the bracket

6x+45-12x =33

-6x=33-45

-6x=-12

x=2

plugging this value of x in equation 2 we get

15-4x=y

15-4(2)=y

y=15-8

y=7

Answer is x=2 and y=7

(x - 3)(x² + 4)

Step-by-step explanation:

x³ - 3x² + 4x - 12 ( factor first/second and third/fourth terms )

= x²(x - 3) + 4(x - 3) ← factor out (x - 3 from each term

= (x - 3)(x² + 4)
