Answer:
each boy ate 8 cookies
Step-by-step explanation:
48-16=32
32 divided by 4=8
so each of them ate 8 cookies
Answer: 8x
2.9543127e+21xy
9x
Step-by-step explanation:
4x^2=16x 28x=28x 36=36 16x+28x-36 16+28=44-36=8x
125x^6= 30517578125x 27y^15= 2.9543127e+21 30517578125x-2.9543127e+21= 2.9543127e+21xy
4-7=3+x=3x 5-8=3+x=3x 3x * 3x= 9x
(x/100-1)(x/100+1)=kx^2-1
(x/100-1)(x/100+1)=(x/100)^2 - 1^2 because it's a difference of squares ( (a-b)(a+b) = a^2-ab+ab-b^2 = a^2 - b^2):
(x/100)^2 - 1^2=kx^2 - 1
(x/100)^2 - 1=kx^2 - 1
(x/100)^2=kx^2
(x^2)/(100^2)=kx^2
1/(100^2)=k
1/10000=k
k=0.0001
