Answer:
1, 3, 5
Step-by-step explanation:
let the 3 consecutive odd numbers be n , n + 2 , n + 4 , then
5(n + 2) = 2(n + n + 4) + 3 ( 5 times 2nd = twice sum of 1st and 3rd + 3 )
5n + 10 = 2(2n + 4) + 3
5n + 10 = 4n + 8 + 3
5n + 10 = 4n + 11 ( subtract 4n from both sides )
n + 10 = 11 ( subtract 10 from both sides )
n = 1
n + 2 = 1 + 2 = 3
n + 4 = 1 + 4 = 5
The 3 consecutive odd numbers are 1, 3, 5
Step-by-step explanation:
let the three consecutive odd number be x + 1 , x + 3 , x + 5
a/q
5 times the middle number = 5(x + 3) is
3 more than twice the sum of 1st and 3rd number = 3 + 2(x+1 + x + 5 )
so,
= 5 ( x + 3 ) = 3 + 2 ( x + 1 + x + 5 )
= 5x + 15 = 3 + 4x + 12
= 5x + 15 = 4x + 15
= -4x + 5x = 15 - 15 = 0
= x = 0
so, the 3 consecutive odd numbers are,
x + 1 = 1
x + 3 = 3
x + 5 = 5
and also a/q
5 times the middle number = 5×3 = 15
is equal to 3 more than twice the sum of 1st and 3rd number = 3 + 2(1+5) = 12 + 3 = 15
LHS = RHS
hope this answer helps you dear...take care and may u have a great day ahead!

4(x-8)+12 equal 2(2x-9)
(Answer explained)
4(x-8)+12=2(2x-9)
We move all terms to the left:
4(x-8)+12-(2(2x-9))=0
We multiply parentheses
4x-(2(2x-9))-32+12=0
We calculate terms in parentheses: -(2(2x-9)), so:
2(2x-9)
We multiply parentheses
4x-18
Back to the equation:
-(4x-18)
We add all the numbers together, and all the variables
4x-(4x-18)-20=0
We get rid of parentheses
4x-4x+18-20=0
We add all the numbers together, and all the variables
-2!=0

-x³-x²+5x-3 find each polynomial by degree and number of terms
Answer:
- (x-1)^2 x (x+3) is correct ans
Step-by-step explanation:
rewrite the expression
-x^3 - x^2 + 5x - 3
factor the expressions
x^3 + x^2 -2x^2 +2x=3x-3
factor the expression
-x^2 x (x-1)-2x x (x-1) +3 (x-1)
rewrite the expression
-(x-1) x (x^2 + 2x-3)
rewrite
-(x-1) x (x^2 + 3x - x - 3)
factor the expression
-(x-1) x (x^2+2x-3)
factor the expression
-(x-1) x (x x(x+3)-(x+3)
write in exponential form
-(x-1) x (x+3) x (x-1)
solution:
-(x-1)^2 x (x+3)

Answer:
f(2) = -2
Step-by-step explanation:
plug in 2 to wherever x is in this statement:
f(2) = -2(2^2) - 2(2) + 10
f(2) = -2(4) - 4 + 10
f(2) = -8 - 4 + 10
f(2) = -2

An angle 0 is drawn on the unit circle such that its terminal ray is in the second quadrant.
if sin 0 = 0.809, then what must be true about sin(-0)?
Answer:
sin(-θ) = -0.809
Step-by-step explanation:
To find this, simply perform the operation that is being asked, make theta negative.
If you want to find out what theta is in the first place, do this:
θ = arcsin(0.809)
θ = 54
Then to find sin of negative theta, substitute:
sin(-θ), or, sin(-54)
should equal to:
sin(-θ) = -0.809
