1) x + 3.2= -3.5
subtract 3.2 from both sides
x+ 3.2 - 3.2= -3.5 - 3.2
it cancels out on the left
x= -6.7
2) 8/9x= 32
divide both sides by 8/9
8/9x ÷ 8/9= 32 ÷ 8/9
it cancels out on the left
to divide on the right, multiply fraction by its reciprocal/inverse
x= 32 * 9/8
multiply numerators (top)
x= (32*9)/8
x= 288/8
x= 36
ANSWER: 1) x= -6.7; 2) x= 36
Hope this helps! :)

Answer:
Step-by-step explanation:
The surface area of a rectangular prism is given by the formula;
From the diagram;
The length is 
.
The width is 
.
The height is 
.
Substitute these values into the formula to obtain;
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
