Answer:
80 m²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h (a + b)
where h is the perpendicular height between bases and a, b are the bases
Here h = 8, a = 14 and b = 6, thus
A = × 8 × (14 + 6) = 4 × 20 = 80 m²
Answer:
<em>We can't find a unique price for an apple and an orange.</em>
Step-by-step explanation:
Suppose, the price of an apple is and the price of an orange is
They need $10 for 4 apples and 4 oranges. So, the first equation will be.......
They also need $15 for 6 apples and 6 oranges. So, the second equation will be........
Dividing equation (1) by 2 on both sides :
Dividing equation (2) by 3 on both sides :
So, we can see that both equation (1) and (2) are actually same. That means, we will not get any unique solution for and
here. Both
and
have <u>"infinitely many solutions"</u>.
Thus, we can't find a unique price for an apple and an orange.
