Answer:
The first one is correct.
Step-by-step explanation:
I know a thing or two about a thing or two about powers of 10.
Hey mate !!
Here's your answer !!
2w^2 - 11w = -12
2w^2 -11w + 12 = 0
2w^2 - 8w - 3w + 12 = 0
2w ( w - 4) -3 ( w - 4) = 0
(2w - 3) ( w - 4) = 0
Hence
2w - 3 = 0
2w = 3
w = 3/2
w - 4 = 0
w = 4
Hence value of w are 4 and 3/2
Hope this helps!!
Cheers!!
Answer:
First one is 25/2
Step-by-step explanation:
12×2+1=25/2
9×4+1=36/4
cross multiply and you get
100/
divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore
Answer:
1. 1,016 sq. m.
2. 119 sq. m.
Step-by-step explanation:
1.
14 x 18 = 252
18 x 8 = 144
14 x 8 = 112
2 ( 252 ) + 2 ( 144 ) + 2 ( 112 )
504 + 288 + 224 = 1,016 sq m
2.
4 (7 x 5 divided by 2) + (7 x 7) =
7 x 5= 35 divided by 2 = 17.5 x 4 = 70 + 49 = 119 sq. m.
I hope this helps
sorry if i'm wrong
