Answer:
a = 2
Step-by-step explanation:
4 (2a + 3) = 28
4 * 2
= 8
4 * 3
= 12
8a + 12 = 28
28 - 12
= 16
8a = 16
16 / 8
= 2
a = 2

Answer:
x-13
Step-by-step explanation:
why you may ask?
subtracted=being taken away from
13 is *being taken away from* x
so if using numbers, 13 is being taken away from 20
or 13 is being subtracted from 20 would be 7, so x-13 would be your expression

Answer:
2x^3−7x^2+16x−15
Step-by-step explanation:
(2x−3)(x^2−2x+5)
=(2x+−3)(x^2+−2x+5)
=(2x)(x^2)+(2x)(−2x)+(2x)(5)+(−3)(x^2)+(−3)(−2x)+(−3)(5)
=2x^3−4x^2+10x−3x^2+6x−15
=2x3−7x2+16x−15
Answer:
2x³ -7x² +16x -15
Step-by-step explanation:
You distribute the (2x-3) onto the other trinomial and then combine the like-terms.
(2x-3)(x²-2x+5)
2x³ -4x² + 10x -3x² +6x -15
2x³ -7x² +16x -15

A math class is having a discussion on how to determine if the expressions 4 x minus x + 5 and 8 minus 3 x minus 3 are equivalent using substitution. The class has suggested four different methods.
Which describes the correct method?
*Both expressions should be evaluated with one value. If the final values of the expressions are both positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.
Answer:
Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.

Name the marked angle in 2 different ways.
The marked angle in 2 different ways will be ∠HLK or ∠KHL and ∠KHL = ∠HLJ - ∠KLJ.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The marked angle in 2 different ways will be given as,
The first way will be
∠HLK or ∠KHL
The second way will be
∠KHL = ∠HLJ - ∠KLJ
The marked angle in 2 different ways will be ∠HLK or ∠KHL and ∠KHL = ∠HLJ - ∠KLJ.

How do you convert mass to volume without density?
Answer:
Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be
The general formula is:
ρ
=
m
V
where
ρ
is density in
g/mL
if mass
m
is in
g
and volume
V
is in
mL
.
So to get the mass...
m
=
ρ
V
Or to get the volume...
V
=
m
ρ
When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.
Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.
These days, you should be able to search for the density of any common object.
When you have the density and volume but not the mass, then just make up a mass.
You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.
