Answer:
1 and 2
Step-by-step explanation:
K+19.5<40 (The less than sign has a line underneath it to show that it is less than or equal to)
Well, when i get a question like this I use trial and error.
for example lets start with -5, -6, -7, and -8= -26
which in this case does equal the target number but lets say it didn't. If you got a number that was to high you start with a lower number and if you got a number that was to low you start with a higher number.
hope this helps!
Answer: Area =4,806 Perimeter = 286 Type: Quadrilateral
Step-by-step explanation:
To find the area you multiply W and L
To find perimeter you add the length of all sides
I don't understand the last part bit i'm just gonna say it's a quadrilateral.
To do this task the best way is always add both "sides" of ratio and divide whole group by this sum.
sum=4+7=11
33:11=3
Now we know how much is 1 and we can multiply by 4 and by 7 to find the answer.
3*4=12 - first group
3*7=21 - second group
Your result is ok.
