D. 10 x 62
If one row needs 62 bricks and there's 10 rows, you multiply them to get how many bricks nick needs
2 1/4 x 1 1/2
= 9/4 x 3/2
= 27/8
= 3 3/8
Answer:
x = -3
x = 7
Step-by-step explanation:
If either term is zero the product is zero
(2x + 6)(x - 7) = 0
2x + 6 = 0
2x = -6
x = -3
x - 7 = 0
x = 7
no real solutions
The conditions for the discriminant are
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then no real solutions
