Answer:
Wdym scientific notations?
Step-by-step explanation:
3.8 x 102 = 387.6
6.4 x 10 = 64
Standard form is
ax+by=c
where a and b and c are integers
and a is normally positivie
y+1/5=3x
minus 3x both sides
-3x+y+1/5=0
minus 1/5 both sides
-3x+y=-1/5
times -5 both sides
15x-5y=1

Answer:
Step-by-step explanation:
8x + 15 = 24
8x = 9
x = 
L=w+2 and 2w+2l=44
substitute equation for length in perimeter equation
2w+2(w+2)=44
2w+2w+4=44
4w+4=44
4w=40
w=10
substitute width into length equation to get length
l=10+2
l=12
a=lw
a=12*10
a=120 cm^2
