The answer is B. 120+24c=500
I believe the correct answer here would be C. x=10/3 because it is the only proportional answer.
Answer:
2
Step-by-step explanation:
f(x) = x^2 + 1
f(-1) = (-1)^2 + 1
f(-1) = 2
x-------> the length of <span>a rectangular cookie sheet
we know that
area of </span><span>a rectangular cookie sheet=length*width
area of </span>a rectangular cookie sheet=192 in²
area of a rectangular cookie sheet=<span>x² + 4x-----> x*(x+4)
</span><span>Step 1: x² + 4x = 192
</span><span>Step 2: x(x +
4 ) = 192 The length is x. The width is
(x+4)
</span><span>Step 3: x² + 4x = 192=0
we have
</span>x² + 4x = 192
x² + 4x - 192=0
using a graph tool-----> to resolve the second order equation
see the aattached figure
the solution is
x=-16
x=12
(x+16)*(x-12)=0
the length is x=12 in
and the width is-----> (x+4)-----> 12+4----> 16 in
<span>Step 4: (x +
16) (x - 12) = 0
Because the length can't be -
16 the length is 12, and the width is
16</span>
Jus give me it I’m too stupid for this
