Explanation:

The sum of something and 2 can only be zero when that something has a value of -2.

The range of the square root function is all non-negative numbers, so it cannot have a value of -2. Thus, the equation cannot have a solution.

Answer:

see explanation

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 12 , then radius = 12 ÷ 2 = 6 , then

A = π × 6² = 3.14 × 36 = 113.04 m²

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here C = 28.26 , then

2πr = 28.26 ( divide both sides by 2π )

r = $\frac{28.26}{2(3.14)}$ = $\frac{28.26}{6.28}$ = 4.5 in

Find the equation of lines

bearhunter [10]

Answer:

y = x + 6.

Step-by-step explanation:

y = mx + c where m = the slope of the line and c is the y-intercept.

So here m = 4/4 = 1 and c = 6, so it's:

y = 1x + 6.

The top left angle measure is ?

Gnesinka [82]

x = 100°

In a parallelogram all the interior angles must add up to 360°

Opposite angles of a parallelogram are equal

360° = x + x + 80° + 80°

360° = 2x + 160°

2x = 200°

x = 100°

Alternatively:

x and 80° are corresponding angles because they are on the same line that crosses two parallel lines. Corresponding angles are complementary and add up to 180°.

180° = x + 80°

x = 100°
