The continent uses and produces many different types and sources of energy,

Primary energy sources include fossil fuels (petroleum, natural gas, and coal), nuclear energy, and renewable sources of energy. They generate electricity, which is a secondary energy source.

However, the source of most of the continent’s electricity is natural gas, with 31.8%. Natural gas is a mixture of hydrocarbon gases that occurs naturally beneath the Earth's surface.

Solve the quadratic by factoring.<br> x^2-5x-31=5
torisob [31]

Answer:

x =  - 4\: or \: x =  9

Step-by-step explanation:

make one side equal to zero:

{x}^{2}  - 5x - 36 = 0

find two factors that multiply to -36 and add to -5 (-9 & 4)

{x }^{2}  - 9x + 4x - 36 = 0

factorise

x(x - 9) + 4(x - 9) = 0

(x + 4)(x - 9) = 0

solve for x

x =  - 4 \: or \: x = 9

What is the area of triangle pqr on the grid? a triangle pqr is shown on a grid. the vertex p is on ordered pair 7 and 6, vertex
horsena [70]

P(7,6), Q(1,6), R(4,2)

We have PQ parallel to the x axis. We'll call that the base,

b = 7 - 1 = 6

The altitude is then the y difference h = 6 - 2 = 4

The area is \frac 1 2 bh = \frac 1 2 (6)(4) = 12

Answer: 12 square units


In general we can use the shoelace formula for the area of any polygon given coordinates. We write the points like this:

(7,6), (1,6), (4,2)

(1,6), (4,2), (7,6)

The area is then half the absolute value of the sum of the cross products:

A = \frac 1 2 | 7(6)-6(1) + 1(2)-6(4) + 4(6)-2(7) | = \frac 1 2 |24| = 12
