-5.8c + 4.2 - 3.1 + 1.4c = -4.4c +1.1
Hope this helps! Ask me any questions if needed :)
Answer:
numbers expressed using exponents are called powers
Pretty Sure it’s y=x+(-.8) haven’t done algebra in a bit. Sorry if wrong. :/
Answer: Congruent
Step-by-step explanation:
Line BC is reflexive to itself
AB is congruent to CD, and that's given
Line AC is congruent to BC, using these prior proofs
Angle EDC and Angle FAB are congruent, and that's a given.
You can conclude that they are congruent by AAS
Answer:
5π m
Step-by-step explanation:
Using the pythagorean theorem we can figure out that the third side is 5m
A^2 + B^2 = C^2
3^2 + 4^2 = C^2
9 + 16 = C^2
25 = C^2
√23 = √(C^2)
C = 5m
Side C is also the diameter of the circle, so the radius is 5/2, or 2.5
From that we can use the circumference formula, Circumference = 2π<em>r</em>
Circumference = 2 π (2.5) = <u>5π m</u>
