So, the problem is 2x - 3x - 2 • 1/7x ?
2x - 3x - 2 • 1/7x
So, combine like terms.
-1x - 2 • 1/7x
-1/7x • 2
The answer would be about -0.3x ?
If I’m understanding correctly.
D) 54 degrees:
BD+AB+DE+2ACE" on the circumference twice on the center"=360
28+112+112+2ACE=360
2ACE=108
∠ACE=54
9-[12(5)] you start with the innermost parenthesis
9-[60] multiply

Answer: The length of BD is 2.4
Step-by-step explanation: BD is a leg of a right triangle, so use the
Pythagorean Theorem a² + b² = c²
BC is the hypotenuse here, so that is c = 3
We can use the segment CD as side b = 1.8
We will call BD side a, and solve to find that length.
a² + (1.8)² = 3² Square the known values of b and c
a² + 3.24 = 9 Subtract 3.24 from both sides.
a² = 9 - 3.24 Simplify
a² = 5.76 Find the square root of both sides (Calculator time!)
a = 2.4
It is t divided by r equals 2s
