Answer:
He can buy 24 roses
Step-by-step explanation:
First, we subtract 3 from 21 to get 18. After that to get the price of each rose, we divide 21 by 0.75 to get 24.
Let's take l and w as the length and the width of the rectangle.
According to the given information the length is 3 less than twice the width:
And the area, which is the product of the length times the width is 14. Using the equation above, we can re write the formula for the area, this way:
Now, we have to solve the quadratic equation using the quadratic formula:
w has 2 values, but for this context, the logic value is 7/2. It means that the width of the rectangle is 7/2.
Now, we can use this value and the first equation to find the length:
The length of the rectangle is 4 and the width is 7/2.
Answer:
125
Step-by-step explanation:
Given
f(x) = 5x²
g(x) = 2x + 3
Now
g(-4) = 2 * (- 4) + 3
= - 8 + 3
= - 5
Also
f(g(-4)) = f( -5)
= 5 * ( -5)²
= 5 * 25
= 125

Answer:
he had 44 books before he bought those 6
Step-by-step explanation:
If you multiply 6 times 2 it is 12, which means if you take away 12 from 100 that is 88. if you divided 88 by 2 (the same thing you did to the 6 to make it 12%) that would be 44.
