Answer:
12
Step-by-step explanation:
A = ½(b1 + b2)h
A = (3 + 5)(3)/2
A = 12

I think this is it I did this when I was in 5th grade so I don't remember that much might wanna check with an adult.
5/6
you can do 2 things here
use a calculator and divide the numerator by the denominator
or the method you're probably meant to use
change each fraction so they all have the same denominator
the common denominator in this case would be 60
5/6*10=50/60
7/12*5=35/60
7/10*6=42/60
the number with the highest numerator would be the larger fraction
in this case, being 50/60 or 5/6
Answer:
Step-by-step explanation:
hello :
the form : g(x)=a/(x+h)+k
1 ) <u>g(x)=7x+17/x+2 :</u>
you can write : 7x+17 = 7(x+2)+3
so : g(x) =(7(x+2)+3)/(x+2) = 7(x+2)/(x+2) +3/(x+2)
g(x) = 7+ 3/(x+2) or g(x) = 3/(x+2) +7 compare with g(x)=a/(x+h)+k
a=3 and k=7 and h=2
2) <u>g(x)=5x-7/x-3 :</u>
you can write same method for 1 ..... here is other method :
g(x)=a/(x-h)+k = (a+k(x-h))/(x-h)
g(x) = (kx+a-kh)/(x-h) h=3
so : k=5 and a-kh = -7
a-(5)(3)=-7 a = 8
g(x) =8/(x-3) +5
Answer:
4
Step-by-step explanation:
You may recognize these as factors of the difference of two squares:
... a² -b² = (a+b)(a-b)
where a=1 and b=i√3.
Then the product is ...
... 1² -(i√3)² = 1 - 3i² = 1 +3 = 4
_____
Of course, i = √-1, so i² = -1.
