Answer:
One solution
Step-by-step explanation:
As a generalization: an equation of degree n has n solutions. A quadratic equation has the second degree and thus two a solutions; a third degree equation has three, and so on. Thus, a first degree (linear) equation has one solution.

Answer:
x=1.75
Step-by-step explanation:
14/3.5=4-2.25=1.75.
The area of any circle is (pi) x (radius)² .
The area of the WHOLE circle in the question is
(pi) x (2.5 cm)²
= (pi) x (6.25 cm²) .
The full circle is made by 360° of central angles.
90° of central angle makes a pie-wedge (sector)
that's exactly one fourth of the circle, so its area
is one fourth of the area of the whole circle.
Area = (1/4) (pi) (6.25 cm²)
= (0.25) (3.14) (6.25 cm²)
= 4.906 cm² .
Rounded to the nearest tenth: 4.9 cm² .
