A
x=y^2-9
x+9=y^2
square root both sides
+-sqrt(x+9)
Answer:
108
Step-by-step explanation:
Jesicca wants to make tarts
She uses 3/4 cup of flour per batch
Jessica has 9 cups of flour hence the number of batches she will make can be calculated as follows
= 9÷ 3/4
= 9÷ 0.75
= 12
= 12×9
= 108
Hence Jessica will make 108 batches of tart
Solution:
<u>Note that:</u>
- Given expression: (x² + 4x) − (x² + 6x − 3)
<u>Remove the brackets</u>
- (x² + 4x) − (x² + 6x − 3)
- => x² + 4x - x² - 6x + 3
<u>Combine like terms</u>
- x²(1 - 1) + x(4 - 6) + 3
- => x²(0) + x(-2) + 3
- => -2x + 3
