Step-by-step explanation:
<h3>Factorize : 9x² - y² </h3>
<h3>Applied Formula = a²- b² = (a + b ) (a - b)</h3>
<h3>9x²- 1 y² : </h3>
<h3> = (3x)²– (y)² [ (3x)² = 9x² ]</h3>
<h3> = (3x+y) (3x–y)</h3>
Answer:
a) Figure B and Figure C
b) Figure C
c) Figure A, Figure B, and Figure C
Step-by-step explanation:
a) Rectangles are shapes that have four sides, and four right angels. Right angles are angles that are 90 degrees.
The only shapes with four sides AND four right angles are Figure C and Figure B.
b) Squares are shapes with four EQUAL sides and four right angles. The only shape with four equal sides and four right angles is Figure C.
c) Parallelograms are any shapes with four sides. All of these shapes have four sides.

Answer:
x<12
Step-by-step explanation:
When Delta(b^2-4ac) is greater than 0, the quadratic equation has two distinct real solutions, when it is equal to 0, the quadratic equation has one real solution, when it is negative, it has no real solutions.
Answer:
11.25 brownies or 11 1/4 brownies
Step-by-step explanation:
If she has 3 pans that each make 10 brownies, she made 3(10) = 30 brownies
If she gave 3/8 of the brownies away, she gave away...
30(3/8) = 90/8 = 11 2/8 = 11 1/4 brownies
