Step-by-step explanation:
Given n = 4
2n = 2* 4= 8
n + 2 = 4 + 2 = 6
3(n + 4) = 3( 4 + 4) = 3 * 8 = 24
Hope it will help :)
Answer:
x = 
Step-by-step explanation:
Given
4x + 6 = 11 ( subtract 6 from both sides )
4x = 5 ( divide both sides by 4 )
x = = 1.25
Answer: x=8
Step-by-step explanation:
Since we are given that ∠ABC and ∠DBC are complementary angles, we know that adding them together should give us 90°. We can use this to solve for x.
6x+13+4x-3=90 [combine like terms]
10x+10=90 [subtract both sides by 10]
10x=80 [divide both sides by 10]
x=8
Now, we know that x=8.
