Step by step solution :
Step 1 :
Equation at the end of step 1 :
((3x2 + 2x) - 1) - (x2 - 3x + 4)
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 2x2+5x-5
The first term is, 2x2 its coefficient is 2 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 2 • -5 = -10
Step-2 : Find two factors of -10 whose sum equals the coefficient of the middle term, which is 5 .
-10 + 1 = -9
-5 + 2 = -3
-2 + 5 = 3
-1 + 10 = 9
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
2x2 + 5x - 5
brainliest plz tried rlly hard on this
The correct answer is the option number 1, which is:
a(v)=√(3V/8)
The explanation is shown below:
To solve this problem you must apply the following proccedure:
1. You must use the formula for calculate the volume of a square pyramid, which is:
V=a²h/3
2. Therefore, when you clear a, you obtain:
3V=a²h
3V/h=a²
a=√(3V/h)
3. You have that heigth is 8, then:
a(v)=√(3V/8)
4. So, as you can see, the correct answer is the option mentioned above.
A. Using the Simple Discount Note formula:
Proceeds = Maturity Value (MV) - Discount; MV = Face Value
Discount = MdT; M = Maturity; d = discount; T = Time
= $12,300*12%*15/12
Discount = $1,845
Proceeds = MV - Discount
= $12,300 - $1,845
Proceeds = $10,455
B. Using the Simple Interest Note formula:
Effective Rate of Interest = Interest / Proceeds*Time
= $1,297.50 / $17,300*180/360
= .15
Effective Rate of Interest = .15 or 15%
C. False. Discount is the interest charged to the principal of the loan.
The correct anwer is C I think... I hope That helps :)

Answer:The answer is 3 & 7
Step-by-step explanation:3 x 7 = 21
3 + (7) = 10
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 10x + 21 = 0
If so, the solution to factor the quadratic equation above is:
(X + 3 ) (X + 7)
To summarize, since 3 and 7 multiply to 21 and add up 10, you know that the following is true:
x2 + 10x + 21 = (X + 3 ) (X + 7)
