Answer:
x = - 20
Step-by-step explanation:
Hello!
We have been given enough information to solve this question!
We know that the length of the rectangle is 2.5, and we also know how to find the area:
A = l × w
But we don't need the area, we need to find the width of the rectangle! You see, we had to multiply the length by the width to find the area.
Now, to find the width, we must flip the problem around and use the opposite of multiplication, which is division.
W = a ÷ l
W = 10 ÷ 2.5
W = 4
Therefore, the width of the rectangle is 4.
we have
------> equation 
------> equation 
Multiply by the equation
------> equation 
Sum equation and equation
Substitute the value of x in the equation
therefore
the answer is the option B
Answer:
Combining like terms is a mathematical process used to simplify an expression or to add or subtract polynomials.
Step-by-step explanation:
How do I combine like terms?
1. Step 2: Combine the coefficients.
2. 5h + 11g + 1h - 8g.
3. (5 + 1)h + (11 - 8)g.
4. 6h + 3g.
5. Step 1: Organize your like terms.
6. 5x + 8x + 10x2 - 7x2 - 4x.
7. Step 2: Combine the coefficients. (5 + 8 - 4)x + (10 - 7)x2 9x + 3x2
The answer would be A 20c/d
