13x-8+7x+4+3x
Combine like terms
23x-4
It can only be simplified. Without an equal sign (=), x cannot be found.
Answer:
She will have $23 left.
Step-by-step explanation:
Answer:
Put a point at (-7,0) and another at (0,-2)
Step-by-step explanation:
2x+7y=-14
Plug in 0
2(0)+7y= -14
7y=-14
y=-2
same thing for x
2x+7(0)=-14
x=-7
The quotient is 215.
3870/18= 215. The answer of two divided numbers is called the quotient
The equation for which square method is possible is x²-8=1
Step-by-step explanation:
For checking which of the equation satisfies the complete square condition, we proceed by checking each of the available options
1). x²+20x=52
Rewriting it as x²+20x-52
This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 1) and independent constant (i.e. 52) is not a perfect square.
2). 5x² + 3x = 9
This equation can be rearranged as 5x²+3x-9=0
This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 5) and independent constant(i.e. 9) is not a perfect square.
3.) x² −8=1
This equation can be rearranged as x²=9
Hence x= ±3
This binomial expression is a perfect square and can be done by the square method.
4). 3x² −x+17=0
This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 3) and independent constant(i.e. 17) is not a perfect square.
