Multiply corresponding components, then add the products:

For example, -7 is an integer<span>, so it is also a rational and a real number. The square root of 2 is an irrational number, so it is also a real number.</span>
Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A =
bh ( b is the base and h the perpendicular height )
here b = 14 and h = 4, hence
A =
(14 × 4) = 28
the answer to that is 0.59
4 * -1 * 3 + 2 = -10
