Answer:
the equation is : x²-x-12
Step-by-step explanation:
the quadratic equation is in the form of : y=ax²+bx+c
the product of the zeros is -12 and the sum is 1
b = - 1
c=-12 (product)
y=x²-x-12
check : factorize first (x+3)(x-4)=0
either x+3=0 then x=-3
or x-4=0 then x=4
-3*4=-12
-3+4=1
the equation is : x²-x-12
The Pythagorean theorem tells you
... a² + b² = c²
so
... a² = c² - b² = 16² - 9² = 256-81 = 175
... a = √175 = √(25·7)
... a = 5√7
Answer:
Step-by-step explanation: FIRST YOU PUT THE NUMBER AND THEN X AFTER THAT YOU PUT THE NEXT NUMBER.
Alright, lets get started.
I hope, the dimensions of rectange are asked in this question.
Suppose the width of rectangle = x in
Given that length of the rectangle is 3 in longer than the width.
It means length of the rectangle = (x+3) in
Now, the area of the rectangle = lenght * width
area of the rectangle = 
area of the rectangle =
The area of a rectangle is 70 in square (given in question)
Equalling both areas

Subtracting 70 in both sides


Factoring

It will give two values of x
x = -10 (which is not possible because length could not be negative)
x = 7
Means width 
length 
Means the dimensions of rectangle are 7 in and 10 in. : Answer
Hope it will help :)
