x + 2 = 0;
x = -2
The root is -2. User: A rectangular photograph is 8 cm wide and 12 cm long. The photograph is enlarged by increasing the length and width by an equal amount in order to double its area. What are the dimensions of the new photograph? a. 12 cm by 16 cm c. 20 cm by 30 cm b. 16 cm by 24 cm d. 48 cm by 72 cm Weegy: The dimensions of the new photograph is: 12cm wide and 16cm long
Solution:
Area of Rectangle = Length * Width
12 * 8 = 96 cm2
Area after the enlargement ( doubled)
96 * 2 = 192 cm2
Equation with length & width after
increasing both dimensions [ by equal amount x:
( x + 12) * ( x + 8) = 192
] User: x^2+ 4 – 45=0 a. {–5, –9} c. {–5, 9} b. {–9, 5} d. {5, 9} Weegy: $0.75 (More)
