Answer:
7
Step-by-step explanation:
When you match the form
... ax² + bx + c = 0
to the equation
... 3x² + 5x + 7 = 0
it is reasonable to conclude that ...
... a = 3, b = 5, c = 7.
_____
The question presumes you are familiar with the form
... ax² +bx +c = 0
which is often used as the representation of a general quadratic equation. This lets us use a, b, and c instead of specific numbers, to talk about ways of factoring, graphing, or solving equations like this.
Acute is the answer ..........

Answer:
7 1/7
Step-by-step explanation:
For the problem:
5
/7
× 10 = ?
Convert any mixed numbers to fractions:
10 = 10
Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
5 × 10
7 × 1
=
50
/7
50 ÷ 7 = 7R1, therefore:
50
/7
= 7 1/7
The result is:
5
7
× 10 = 7 1/7
