Answer:
1. 16x2−40x+25
Perfect Square Trinomial
2. x2−2x−8
Trinomial when A>1
3. 3x2+6xy+9xy2
Greatest Common Factor (GCF)
4. 64x2−100
Difference of Squares
5. 27x3+8y6
Sum of Cubes
6. 64x9−y3
Difference of Cubes
7. 6x2+19x+15
Trinomial when A=1
8. 6x3+3x2+8x+4
Grouping
Step-by-step explanation:
A trinomial is a polynomial which has three terms.
1. 16x2−40x+25
(4x)2 - 2(4x)(5) + (5)2
= (4x-5)2
Perfect Square Trinomial
2. x2−2x−8
= x2 - 4x+2x-8
= x(x-4) +2 (x-4)
= (x+2)(x-4)
Trinomial when A>1 ( when we will put x= 1 we will get a negative value)
3. 3x2+6xy+9xy2
=3x(x+2y+3y2)
(3x is common)
Greatest Common Factor (GCF)
4. 64x2−100
= (8x)2- (10)2
= (8x-10)(8x+10)
Difference of Squares
5. 27x3+8y6
=(3x)3+(2y2)3
= (3x+2y)(6x2-6xy+4y2)
Sum of Cubes
6. 64x9−y3
= (4x3)3- (y)3
Difference of Cubes
7. 6x2+19x+15
= 6x2 + 9x + 10x + 15
= 3x( 2x+3) + 5(2x+3)
= (2x+3)(3x+5)
Trinomial when A=1
8. 6x3+3x2+8x+4
Grouping
Grouping usually has four or more terms
6x3+3x2+8x+4
=3x2(2x+1) + 4(2x+1)
=(3x2+4) (2x+1)
Answer:
Step-by-step explanation:
The equation of proportionality is
y = kx ← k is the constant of proportionality
Given
y = = x ← in form y = kx
with k =
Answer:
Part A:
- What We Need to Find is How Much money He Made over the summer
Setting Up the Problem We Would Do 160 + 180 Because we are trying to figure how Much money he made over the summer.
160 + 180 = 340
So Javonie Made 340$ over the Summer
Part B:
Determine what you need to fine?
We trying to figure Out How Much he charged per dog?
To Set up this Problem We are going to Divide 160 Divided By 8
and 180 divided by 9
160 Divided by 8 is 20 In July
180 divided by 9 is 20
so the Answer Is Javonie Charged 20$ per dog in July.

•now find the square root which is....
4.03 cm
The units of the initial and final rates of speed are;
<u><em>Initial rate of Speed = ft/hr</em></u>
<u><em>Final rate of speed = mi/min</em></u>
- We are told that the conversion factors he used are;
5280 ft/1 mi and 1 hr/60 min
- Now, the meaning of 5280 ft/1 mi denotes that;
5280 ft mile is equivalent to 1 mile
This means that the initial distance <em>unit </em>used was ft while the final one was mile
Also, 1 hr/60 min denotes that;
1 hour is equivalent to 60 minutes.
This means that the initial time units used was hour while the final one was minute.
- In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.
