Hi! So, here’s what I know. Every triangle will equal to 180*. So to check if that triangles is 180 we add all angles and it should add up to 180*.
Now the question is, Why it shows that the angles of a triangle equal to 180* when added up?
Note that we see all angles lie on a straight line, therefore we know that when we add angles that lie on a straight line it will equal to 180*, they will also meet at the same point.
This is all I can help with. Hope it helped something!!! Have a great day!
Your answers are Equation A (8(4+x) = 72, and Answer C (5 hours).
1) Figure out how much of the total money she earned on Friday. 4*8= 32
2) She has 72 dollars total and 32 dollars were earned on Friday, meaning the rest was earned on Saturday. 72-32= 40
3) She earned 40 dollars on Saturday for 8 dollars an hour, so now you divide 40 by 8 and you get 5. She worked 5 hours on Saturday.
Answer:
x = −10 and x = 4
Step-by-step explanation:
x2 + 6x = 40
Subtract 40 from each side
x^2 + 6x -40 =0
Factor, what 2 numbers multiply to -40 and add to 6
10 * -4 = -40 10+-4 = 6
(x+10) (x-4) = 0
Using the zero product property
x+10 =0 x-4=0
x=-10 x=4
