Perpendicular lines and intersecting lines are the same because they both describe 2 lines that cross one another...
They are different because perpendicular lines cross one another in a specific way. The intersection of perpendicular lines forms 90 degree angles, while intersecting lines just describes 2 lines crossing. It could be at any angle.
Answer:
amaro
Step-by-step explanation:
amaro has double the amount of cards as mateo and mateo has more than agustin, therefore amaro has the most cards.
Answer:
$ 0.08 cents per foot
Step-by-step explanation:
add all of the numbers then subtract by 58.35 and divide by 300 and remove the negative
First, think of it as 3 different expressions.Go through them one at a time. There is:
-2a(a+b-5) ] +3(-5a+2b) ] +b(6a+b-8)
Multiply everything out.] Multiply everything out. ]Multiply everything out
-2a x a = -2a² ] +3 x -5a = -15a ] +b x 6a = 6ab
-2a x b = -2ab ] +3 x 2b = 6b ] +b x b = b²
-2a x -5 = 10a ] -15a + 2b = -15a+2b ] +b x -8 = -8b -2a² + -2ab + 10a = ] ] 6ab + b² + -8b =
-2a²+-2ab+10a ] ] <span>6ab+b²+-8b
</span>Now add everything up, but before that, remember these algebraic rules:
∞A.S.S. Add Same Signs, meaning positive add positive or negative add negative equals a positive number or 0. E.g 1+1=1 and -1+-2= 1
∞S.I.D. Subtract If Different, meaning a positive number add a negative number always equals a negative number or 0. E.g 1 + -2 = -1
∞You can only add up "similar terms", meaning you can add 'terms' ending in 'a' for example with another 'term' ending in 'a'. However. you cannot add a term ending in 'a' to an 'ab' or an 'a²'.
Following these rules, -2a²+-2ab+10a+-15a+2b+<span>6ab+b²+-8b =
</span>4ab-5a-6b+b²-2a²
Hope that helps you and that it wasn't too tricky to understand. :)
Since it as at the same time and place.
Let x be the length of the shadow of the 40-ft pole.
The ratio from 30 and 8 would have to be the same as 40 and x.
30:8 = 40:x
30/8 = 40/x Cross multiply
30x = 40*8
x = 40*8 / 30 = 32/3 = 10.67
Length of shadow for 40ft is 10.67 ft.
inches, that is 4 cubic inches. 
inches boxes we calculate:
So it's also 32 such small boxes!
