Distribute, combine like terms, and boom! Hope this helped! (FOIL method)
Area for a triangle:
A= 1/2*b*h
Base= 6 units Height= 5 units
A= 1/2*6*5
A= 1/2*30
A= 15 units^2
15 units^2 is the answer.
I hope this helps!

Answer:
I'm not sure what all that extra stuff is supposed to mean, but the answer to the top question is: x = -6
Step-by-step explanation:
Answer:
7+<u>21</u>+15+19+.....+79
Here 21 be replaced by <u>11</u>.
Now., common diffrence btw terms , d = 11-7 = 4
first term , a = 7
Last term , l = 79
number of terms = ( a + l ) ÷ d
=( 7 + 79 ) ÷ 4 = 86 ÷ 4 = 21.5 { It cannot be in decimal }
