It's many things, it's a binomial, an expression, a linear model.
Answer:
x=3
Step-by-step explanation:
To solve for x in the given equation,follow the steps below.
2-(3x-4)=2x-9
clear bracket
2-3x+4=2x-9
6-3x=2x-9
collect like-terms
2x+3x=6+9
5x=15
divide bothsides by 5
Answer:
Length=17
Width=4
Step-by-step explanation:
Length=x
Width=2x-30
x(2x-30)=68
2x²-30x=68
2x²-30x-68=0
2(x²-15x-34)=0
2(x+2)(x-17)=0
So x equals either 17 or -2. Since it can’t be -2, x=17
Length=x=17
Width=2x-30=2*17-30=34-30=4
If it's a perfect square, then it's easy. However, if it's not a perfect square, use the square root button on your calculator. IF you happen to know calculus then you could use Newton's Method....but I'm thinking you're not there yet. So stick with the calculator.
