plz thank me and mark me as brainliest, it keeps me motivated to answer more of your questions :)
First off, we are looking for the area of a poster that's in the shape of a rectangle.
Since we are looking for the area of a rectangle, we need to know the formula for the area of a rectangle.
The area of a rectangle is defined as Length times Width (L x W).
Our length is 3 ft and our width is 2 ft.
Given this information, we are ready to solve.
(L x W) = A
Plug in 3 for the length.
(3 x W) = A
Plug in 2 for the width.
(3 x 2) = A
3 x 2 = 6.
The area is 6 ft^2.
I hope this helps!
Answer:
Yes, see the explanation.
Roots:
x = , or x= -10
Step-by-step explanation:
A quadratic fomrual in standard form is;
ax^(2) + bx + c = 0
The given equation:
4x^2 = -9x - 4
Maniplate the equation using inverse operations
4x^2 = -9x - 4
-4x^2 -4x^2
0 = -4x^2 - 9x - 4
Yes, this is a quadratic equation, because it fits the requirement of being able to be written in standard form.
Now find its roots:
-4x^2 -9x - 4 = 0
remember,
x =
Substitute in the given values
x=
Simplify,
x =
x =
x =
or
x= -10
