The equivalent expression is 2(4x+3)
Answer:
x = 4.
Step-by-step explanation:
The 2 trapezia are similar so we have:
x/ 10 = 2/5
5x = 20
49π or 153.938 mm²
Area of a Circle Formula: A = πr²
Since we are given radius <em>r</em>, simply plug it into the formula:
A = π(7)²
A = 49π
A = 153.938
answer: positive 3
when x=-2 y=3
