What is the product of (x-3) and (x+7)?
First multiply the x's:-
x•x=x²
Now multiply x times 7:-
7x
So we have
x²+7x
Now multiply -3 times x:-
-3x
So we have
x²+7x-3x
Now multiply 7 and -3:-
x²+7x-3x-21
On simplification,
x²+4x-21
<h3>Good luck.</h3>

Answer:
Step-by-step explanation:
The area is: 34/3 feet
I hope I helped :)
B= 12 inches
Perimeter of the triangle= 36 inches
The value of x in the equation 1 1/5 - x/3 = 9/10 is 9/10
<h3>Fraction</h3>
1 1/5 - x/3 = 9/10
- x/3 = 9/10 - 1 1/5
- x/3 = 9/10 - 6/5
-x/3 = 9-12 / 10
-x/3 = -3/10
- divide both sides by - 1/3
x = -3/10 ÷ - 1/3
= -3/10 × -3/1
x = 9/10
