Answer:
Length=22.5cm, Breadth=11.5cm
Step-by-step explanation:
Let length be l and width be w.
w+22=l
w+w+w+22+w+22=90
4w=90-22-22
=46
w=46 divided by 4
=11.5
l=11.5+11
=22.5
Hence,
Length of rectangle=22.5cm
Breadth of rectangle=11.5cm
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) we know that
To put factor back into the square root, we have to put squared value
we have
Remember that
substitute in the expression above
Part 2) we have
Solve for x
That means----> Isolate the variable x
Multiply in cross
Apply distributive property
Group terms
Factor x left side
Divide by (2c-ab) both sides
The answer is 2,4,6,and 8
Answer:
- yes, as written
- no, as simplified
Step-by-step explanation:
The equation can be simplified by subtracting 2x² from both sides. Doing that leaves a linear (not quadratic) equation:
y = 3x
__
A quadratic equation is a polynomial equation such that the exponents of the variables in a term have a maximum total of 2. Here, the terms 2x² match that requirement, making this a quadratic equation.
Answer:
Best answer would be 1/2. If that doesn't work then 0.5/1 would be the answer.
