Answer:
the answer is a polynomial 10x + 2
Step-by-step explanation:
Length = 3x + 2
Width = 2x - 1
Perimeter = 2l + 2w
P = 2(3x+2) + 2(2x-1)
P = 6x+4+4x-2
P= 10x+2
A polynomial is an expression consisting of variables. They can have one or more terms.
Your first step would be to unsolve the zeros, which would leave you with x-1, x-1, and x+2. Then arrange the zeros in the position of a factored polynomial, such as (x-1)(x-1)(x+2), and then FOIL the first two terms. You would then end up with, x^2-2x+1(x+2). After this just finish unfactoring the polynomial.
Your answer would be:
1x^3+0x^2+-3x+2
Answer:
(C)On a coordinate plane, 2 rays form an angle. One ray sits on the x-axis.
Step-by-step explanation:
In the coordinate plane, an angle is said to be in standard position when its value is stated with respect to the x-axis.
Therefore, for an angle to be in a standard position, one of its rays must be on the x-axis.
From the given options, only Option C has a ray that sits on the x-axis. Therefore, it is the only angle in standard position.
Answer: 0.6 in 10 % ; 0.4 in 15 %
Step-by-step explanation:
1. (x*10%) + (y*15%)/ x+y=12%
2. x+y = 1 x= 1-y
(0.1x + 0.15y/ x+y= 12/100) * 100
(10x + 15y/x+y = 12)*(x+y)
10x+15y= 12x + 12y
-2x=-3y
2x = 3y 2(1 - y)= 3y
2-2y=3y 2= 5y
y= 0.4
x= 0.6
Answer:
15 times the first equation and -12 times the second equation
Step-by-step explanation:
we have
------> first equation
------> second equation
Multiply the first equation by 15 both sides
-----> new first equation
Multiply the second equation by -12 both sides
-----> new second equation
Adds the two new equations
The y-term was eliminated
