Answer:
x = 7 ± 
Step-by-step explanation:
Given
4(x - 7)² - 48 = 12 ( add 48 to both sides )
4(x - 7)² = 60 ( divide both sides by 4 )
(x - 7)² = 15 ( take the square root of both sides )
x - 7 = ±
( add 7 to both sides )
x = 7 ±

Answer:
3x^2−13x+4
Step-by-step explanation:
(x−4)(3x−1)
=(x+−4)(3x+−1)
=(x)(3x)+(x)(−1)+(−4)(3x)+(−4)(−1)
=3x^2−x−12x+4
=3x^2−13x+4
The width of the enlarged photo is 9 inches.
Given:
Original length = 2 inches
Original width = 1 inch
Extended length = 18 inches
Extended width = ?
2:1 = 18:x
2x = 1*18
2x = 18
2x/2 = 18/2
x = 9 * extended width.
to check:
2:1 = 18:9
2*9 = 1*18
18 = 18
