Consecutive odd numbres are 2 apart
they numbers are x and x+2
square of first plus 3 times 2nd is 24
first is x
2nd is x+2
x²+3(x+2)=24
easy
x²+3x+6=24
minus 24 both sides
x²+3x-18=0
factor
(x+6)(x-3)=0
set to ezr
x+6=0
x=-6
false, this is even
x-3=0
x=3
x+2=5
the numbers are 3 and 5
9+15=24, yah
3 and 5 are numbers
Answer:
closest to -3/5 is -4/5. closest to 4/5 is 0.6
Step-by-step explanation:
<em> a₁ is the first term, d is the difference, and n is the term</em>
a₁ = -5
d = -5
<em>explicit formula</em>
<em>recursive formula</em>
Answer:
4 is your answer
Step-by-step explanation:
in triangle
60+70+13x-2=180 sum of interior angle of the triangle is 180
128+13x=180
13x=180-128
x=52/13=4
X+y=8
2x^2-y=-5
elimination method means you link the 2 equations together to make one
these two already have y in the perfect form where you can cancel it out +y and -y so no need to perform any other action to a certain equation.. all you need to do is add them now
2x^2+x=3
