Answer:
step by step below
Step-by-step explanation:
14. y = x²+4x+1
y=x+1
x+1 = x²+4x+1
x²+3x=0 x(X+3)=0
x=0 or x=-3
18. y=x²-3x-20
y=-x-5
-x-5 = x²-3x-20 x²-2x-15 = 0 (x-5)(x+3) = 0
x=5 or x=-3
20. y=x²+5x+1
y=x²+2x+1
x²+2x+1 = x²+5x+1 3x = 0
x = 0
22. y=-x²-3x-2
y=x²+3x+2
x²+3x+2 = -x²-3x-2 2x²+6x+4 = 0 2(x²+3x+2) = 2 (x+1)(x+2) = 0
x = -1 or x = -2

Paige goes shopping and buys leggings for $24.95, a crewneck for $30.50, and a new purse (p). She says the expression 5.55+p can be used to find her total. Explain what she did wrong when writing her expression and write a new expression that correctly describes her total.
Answers
Answer:
[tex]55.45+p[/tex]
The decimal point is one step behind and rounded the number.
Step-by-step explanation:
Cost of leggings = $24.95
Cost of crewneck = $30.50
Cost of new purse = p
The correct expression to find the total cost of her shopping is
[tex]24.95+30.5+p[/tex]
[tex]=55.45+p[/tex]
What Paige did was she put the decimal point one step behind and rounded the number.
[tex]2.495+3.05+p[/tex]
[tex]=5.545+p[/tex]
[tex]=5.55+p[/tex]
So, she got the wrong expression.

Answers
Step-by-step explanation:
1. You already got the first step, where D is the midpoint of AC and AB is congruent to BC, since it's given.
2. AD will be congruent to DC, via the definition of a midpoint (a midpoint is the middle point of a line segment, and it splits the segment into two congruent parts)
3. BD is equal to BD, via reflexive property. ( It's a shared side between the two triangles)
4. that means that ΔADB ≅ΔCDB via SSS rule.
5. ∠ABD ≅∠CDB by CPCTC (corresponding parts of congruent triangles are congruent)

Because the numerator and denominator of the fraction are equivalent, the value of the fraction is __________ o Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label) o In order for units to cancel they must be in _____________________________ of the fraction.
Answers
Answer:
The answer is below
Step-by-step explanation:
A fraction is the ratio of the numerator to the denominator. It is given as:
Fraction = numerator / denominator.
If both the numerator and denominator are equal then:
numerator = denominator
Fraction = numerator / denominator = numerator / numerator = 1
When using fractions with units, if you want the units to be canceled out the both the numerator and the denominator must have the same units.
Because the numerator and denominator of the fraction are equivalent, the value of the fraction is 1. Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label) o In order for units to cancel they must be in both numerator and denominator of the fraction,

Convert 345 degrees to radians.
Answers
Answer:
6.02139
Step-by-step explanation:
345° × π/180 = 6.021rad
The number 345 degrees can be written in the form of radians would be 23π/12 radians.
Used the concept of measurement unit which states that,
A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.
Since,
1 degree = π/180 radians
Now, convert 345 degrees to radians as,
1 degree = π/180 radians
345 degree = 345 × π/180 radians
= 23π/12 radians
Therefore, we get;
345 degree = 23π/12 radians
