Answer:
<h2>(x-4)</h2>
Step-by-step explanation:
Step 1 : Write +2x as a difference
= x^2-4x+6x-24
Step 2: Factorize out common terms
= x(x-4)+6(x-4)
Factorize out (x-4)
(x-4)(x+6)
2x - 4 = 40 so I put 4 under both of them and crossed it out
2x = 44 I got rid of the -4 on the left side
X=22 I got rid of the 2 on the left side by dividing it and making the answer for 1 x be simple and x=22
Largest doll = 12 inches
2nd doll = (12) x 0.7
3rd doll = (12 x 0.7) x 0.7
4th doll = [(12 x 0.7) x 0.7) x 0.7
So, the height of the nth doll can be expressed as: 12 x 0.7^(n-1)
Example: 4th doll = 12 x 0.7^(4-1) = 12 x 0.7^3
Answer:
(1, - 12 )
Step-by-step explanation:
Moving left 3 units means subtracting 3 from the x- coordinate
Moving down 6 units means subtracting 6 from the y- coordinate
(4, - 6 ) → (4 - 3, - 6 - 6 ) → (1, - 12 )
