Answer:
56 - 28d
Step-by-step explanation:
1) First, combine the like terms within the parentheses. So, add 2 and 6 together:
2) Then, use the distributive property to simplify further. To use the distributive property, you need to multiply all the terms within a set of parentheses by the number that needs to be multiplied next to it. So, in this case, multiply both 8 and -4d by 7:
Since we cannot simplify further or combine like terms, 56 - 28d is the simplified expression.

Answer:
Option A is correct.
Step-by-step explanation:
Given an isosceles trapezoid has base angles of 45° and bases of lengths 8 and 14. we have to find the area of isosceles trapezoid.
An isosceles trapezoid has base angles of 45° and bases of lengths 8 and 14.
From the figure attached , we can see an isosceles trapezoid ABCD,
AB = 8cm and CD=14cm
So we have to find the value of AE which is the height of Trapezoid in order to find area.
In ΔAED
⇒
∴ AE = DE =3cm
h=3cm, a=14cm, b=8cm
hence,
Option A is correct.
