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.
