X2 + 6X +8
the answer is C. 4
A radius perpendicular to a chord bisects the chord, so the answer is twice 4.5
Answer: C. 9
Answer:
x=8a
Step-by-step explanation:
(3/a) x - 4 = 20
add 4 to both sides
(3/a) x = 24
Divide by 3/a
x = 24 / (3/a)
Use KCF (keep change flip)
x = (24/1) x (a/3)
x = 24a / 3
simplify
x = 8a
Answer:
x = 2/3; all real numbers.
Step-by-step explanation:
• hey! •
let's move step-by-step to evaluate these equations.
1. 28 - 6x + 4 = 30 - 3x
- group like terms -
- add! -
- subtracting and simplifying -
- simplify -
.
2. 4x - 1 = 9x - 1 - 5x
- add -
- simplify -
- add -
thusly, are solutions to the equation. :)
