Answer:
3 ft by 4/3 feet.
Step-by-step explanation:
We have been given that a card is 9 inches by 4 inches. A printing shop will enlarge it so that the longer side is any lengths up to 3 ft. We are asked to find the dimensions of biggest enlargement.
We will use proportions to solve our given problem.

Upon substituting our given values, we will get:




Therefore, the dimensions of the biggest enlargement would be 3 ft by 4/3 feet.
1.66e+9 watts is what that is equivalent to
Answer:
x=1/2, x=-5/3
Step-by-step explanation:
The x intercepts are where y =0
f(x)=4(2x-1)(3x+5)
0 = 4(2x-1)(3x+5)
Using the zero product property
2x-1 =0 and 3x+5 =0
2x-1+1 =0+1 3x+5-5=0-5
2x=1 3x=-5
2x/2 = 1/2 3x/3 =-5/3
x = 1/2 x = -5/3
