Answer:
x = 5
Step-by-step explanation:
6(3 - 7x) = -192
Divide each side by 6
6/6(3 - 7x) = -192/6
3 - 7x = -32
Subtract 3 from each side
3-7x-3 = -32-3
-7x = -35
Divide each side by -7
-7x/-7 = -35/-7
x = 5
Answer:
8494.87 is the actual answer but the rounded version is 8494.9
12 feet and 10 inches would be how long it is. please give a thanks
The length of the enlarged garden is x + 3 + 8 feet, or x + 11 feet. Dividing this into the given area x^2 + 20x + 99 produces the quotient x + 9.
The dimensions of the enlarged garden are (x+11) by (x+9). Note that mult. these 2 factors together produces x^2 + 20x + 99, as expected.
Length of enlarged garden is x+11, whereas the width is x+9. Thus, the difference between length and width of the enlarged garden is 2 feet.
