Move the -3 to the other side which makes it 41 + 3 = 44
So now the equation looks like 4x=44
Now divide 44 by 4, equals 11
x=11
Hmm, so that means that the diagonal of the square is 8
we draw and get a right triangle
pythagorean theorem
the legs are the same measure since it's a square
the hyptonue is 8
so
remember if the legs are a and b and the hypotnuse is c then
a²+b²=c²
alrighty
a=b
c=8
a²+a²=8²
2a²=64
divide both sides by 2
a²=32
sqrt both sides
a=√32
wait, the area is side times side, but it's a square so it's side² which is a²=32
the area is 32
answer is A
Answer:
yes
Step-by-step explanation:
A) the equation accuretly models this scenario because Emanuel has a total of 48 cards. He bought some (X) and his aunt gave him 18. In order to find the number of cards he bought you set the number of cards he bought and the number of cards he got from his aunt equal to the number of cards he has.
B) 48= X + 18
Subtract 18 over
30=X
He bought 30 cards from the store.
48+ 30+18
