Hi there!
You would have to simplify the terms inside [ ] this thing, then multiply.
So let's simplify them first.
4 - (3c - 1)
use distributive property.....
4 - 3c + 1
-3c + 5
6 - (3c - 1)
use distributive property again...
6 - 3c + 1
-3c + 7
so now, multiply (-3c + 5)(-3c + 7).
(-3c + 5)(-3c + 7)
9c² - 21c - 15c + 35
9c² - 36c + 35
So your final answer is...
9c² - 36c + 35
Hope this helped! :)
25/x=100/20 criss cross and u will get 500/100=5 then 5 students resivs A.
Answer:
15 a^2 + -10 a b
Step-by-step explanation:
Expand the following:
5 a (-2 b + 3 a)
Hint: | Distribute 5 a over -2 b + 3 a.
5 a (-2 b + 3 a) = 5 a (-2 b) + 5 a (3 a):
-2 5 a b + 5 3 a a
Hint: | Combine products of like terms.
5 a×3 a = 5 a^2×3:
5×3 a^2 - 2×5 a b
Hint: | Multiply 5 and 3 together.
5×3 = 15:
15 a^2 - 2×5 a b
Hint: | Multiply 5 and -2 together.
5 (-2) = -10:
Answer: 15 a^2 + -10 a b
Answer:
m<AEB = 46°
Step-by-step explanation:
Given:
Arc AD = 161°
Arc BC = 107°
Required:
m<AEB
Solution:
Vertex angle = ½(sum of intercepted arcs) => Theorem for angle inside a circle and its intercepted arcs)
This:
m<AED = ½(AD + BC)
m<AED = ½(161 + 107) => Substitution
m<AED = ½(268) = 134°
✔️m<AEB = 180° - m<AED => Linear pair theorem
m<AEB = 180° - 134° => substitution
m<AEB = 46°
