Answer:
46 units^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is
SA = 2(lw +lh+wh) where l is length, w is width and h is height
SA = 2 (2.5* 4+ 2.5*2 + 4*2)
= 2 (10+5+8)
= 2( 23)
= 46 units^2
Answer:
Sarah = 78
Lee = 79
Step-by-step explanation:
98 + 100 + 65 + 78 + 98 + 46 + 100 + 100 + 45 + 50 = 780
780÷10= 78
97 + 67 + 89 + 99 + 100 + 45 + 79 + 89 + 58 + 67 =
790
790÷10=79
Testing my knowledge on this one.
A - when doing a 180 degree rotation, the coordinates (x,y) would become
(-x,-y), in other words, the inverse of the numbers in the x and y
places, (-1,2)->(1,-2)
B - when reflecting over the x axis, only the y coordinate inverts, (x,y) becomes (x,-y), (1,-2)->(1,2)
Answer:
Step-by-step explanation:
121+7x-4=180
7x-4=180-121=59
7x=59+4=63
x=63/7
x=9
It will be nice if you give me brainliest. Good luck!
Answer:
n=0
Step-by-step explanation:
-10n + 24 + 24n = -6n + 24 is the equation you are given
The first thing I did was combine like terms (-10n and 24n)
I should look like this... 14n+24=-6n+24
The second thing I did was add the 6n to 14n. Remember when you switch the sides of a number/letter in an equation the sign in front of it needs to change.
It should look like this... 20n+24=24
The third thing I did was take 24 and 24 and subtract them. You will get 0.
It should look like this... 20n=0
The last thing to do is divide 0 and 20. That will equal 0!
It should look like this... n=0
I hoped I helped. If you have any more question about his problem let me know! Good Luck. God Bless. Stay Safe. Max Larson
