Step-by-step explanation:
x(2)y(4)z(5)xy(2)
Answer:
27/100
Step-by-step explanation:
27%= 0.27= 27/100 which cannot be reduced
Answer:
In technical terms, the slope of the line is the change in y over the change in x. But I just like to think of it as rise over run. To find the slope of the line, pick two points on the line
The solution fo image problem
Volume= height x width x depth
Volume (cube)=side³
a)
Vt=total volume
V₁(1 foot)=(1 foot)³=1 foot³
V₂( x feet)=( x feet)³=x³ feet³
Vt(x)=V₁+V₂=(1+x³) feet³
Solution: Vt(x)=(1+x³)
Vt= total volume of two cubes
b)x³+1=(x+1)(x²-x+1)
1 0 0 1
-1 -1 1 -1
------- ----------------------------
1 -1 1 0
c)
if x=3 feet.
V(3)=1+3³=1+27=28 feet³
Solution: if x=3 feet ⇒V=28 feet³
The solution of your comments
A)
V(a,b)=(2a)³+(3b)³=8a³+27b³
V(a,b)=8a³+27b³
B)
(x³+y³)=(x+y)(x²-xy+y²)
V(a,b)=8a³+27b³=(2a+3b)(4a²-6ab+9b²)
V(a,b)=(2a+3b)(4a²-6ab+9b²)
C)
a=2 foot
b=4 foot
V(2,4)=2³+4³=8+64=72 feet³
Answer: no; A 1 X 5 rectangle has a perimeter of 12 units and does not have an area of 6 units, so a counterexample shows that your friends statement is not correct
