Answer:
=
Step-by-step explanation:
Given that:
=(1 - 3n3 + 2n4) + (8n4 – 13 – 7)
By opening the brackets we get:
= 1-3n3 +2n4 +8n4 -13 -7
By adding like terms: Constants into constants and variables with same powers of x.....
= -20 - 3n3 +10n4
So by arranging the answer in decreasing order of powers of x:
=

Answer:
<em>B. Triangles A and C</em>
Step-by-step explanation:
Let's find the missing angle of all Triangles:
Triangle A: 180-110-30=40°
Triangle B: 180-30-45=105°
Triangle C: 180-110-40=30°
All triangle angles in numerical order:
ΔA: 30, 40, 110
ΔB: 30, 45, 105
ΔC: 30, 40, 110
We see that only ΔA and ΔC are congruent with the same angle sizes.
Base times height is the formula for area I’m pretty sure
Answer:
Step-by-step explanation:
First rule I'm going to use is the quotient rule:
Secondly, I'm going to rewrite the radical.
Third, I'm going to use the product rule on the first term:
Fourth, I'm going to use power rule for both of the last two terms:
