Answer:
c = 5
Step-by-step explanation:
A quadratic equation in standard form is
ax² + bx + c = 0 : a ≠ 0
Given
- 6 = x² + 4x - 1 ( add 6 to both sides )
0 = x² + 4x + 5 ← in standard form
with c = 5
20/35 and 21/35. The common denominator is 35.
I'm going to assume you meant crayon instead of can:
First step is to find how many boxes she/he has left.
30 - 10 = 20
So the teacher has 20 boxes left;
Now, knowing that each box has 16 crayons, then we simply multiply the 20 by 16 to find the total number of crayons left over:
20 x 16 = 320
So the art teacher has 320 crayons left over.
Hope this helps!
