Answer:
10
Step-by-step explanation:
Here it's given that the area of the shaded region is 48 u² and we need to find out the value of x .
The given figure is made up of two rectangles where the smaller one is inscribed into the bigger one .
- The area of shaded region will be equal to the difference of the areas of the two rectangles , that is equal to 48 u² .
- The area of rectangle is length × breadth .
- The dimensions of bigger rectangle is (x+3)(x-4) and that of smaller one is 3 × x .
So that ,
ar(bigger) - ar(smaller) = 48
[ (x+3) (x-4)] - 3(x) = 48
[ x² - 4x +3x -12 - 3x ] = 48
x² -4x -12 -48 = 0
x² - 4x - 60 = 0
x² - 10x + 4x - 60 = 0
x( x -10) +4(x -10) = 0
(x +4)(x-10) = 0
x = -4,10
- Since sides can't be negative ,
x = 10

Hence the required answer is 10.</h3>
Answer: D) -304
Step-by-Step Solution:
=> f(x) = 5x - 1
=> g(x) = 2x^2 + 1
=> Find value of (f * g)(-3)
First Substitute x as -3 in f(x) and g(x) :-
f(x) = 5x - 1
f(-3) = 5(-3) - 1
f(-3) = -15 - 1
=> f(-3) = -16
g(x) = 2x^2 + 1
g(-3) = 2(-3^2) + 1
g(-3) = 2(9) + 1
g(-3) = 18 + 1
=> g(-3) = 19
Now Multiply f(-3) with g(-3) :-
= f(-3) * g(-3)
= -16 * 19
=> -304
Therefore, (f * g)(-3) = -304
Answer:
50
Step-by-step explanation:
because 250 g = 20 cookies
500g = 40 cookies
625 = 50 cookies
120 g = 20 cookies
240 g = 40 cookies
360 g = 60 cookies
but you only able to make 50 from butter so the answer is 50
