<u>Given</u>:
It is given that the height of the rectangle is 
The width of the rectangle is 
We need to determine the area of the entire rectangle.
<u>Area of the rectangle:</u>
The area of the rectangle can be determined using the formula,

Substituting the values, we have;

Multiplying each term within the parenthesis, we get;

Simplifying, we get;

Adding the like terms, we have;

Thus, the area of the entire rectangle is 
First, multiply 1/4 by x+3 ⇒(1/4x+3/4). Next, multiply 3 by 1+x ⇒(3+3x). The equation should now look like this: 1/4x+3/4-4x≤3+3x. The next thing you have to do is get all of the x's on one side of the symbol. Subtract 1/4x from both sides, and the equation then looks like this: 3/4-4x≤3+2 3/4x. Add the -4x to both sides, and the equation should look like this: 3/4≤3+6 3/4x. Next, you have to move the 3 to the left side. To do that, subtract it from both sides. The equation then look like this: -2 1/4≤6 3/4x. Then, to get the x alone, you need to divide the coefficient (6 3/4) by -2 1/4, which equals -1/3 or -0.3 repeating. So, -1/3≤x
6 + y × 9 (the x is a times sign btw)
The missing angle is ninety degrees (Brainliest please)
