Answer:
![\rm Numbers = 4 \ and \ -3.](https://tex.z-dn.net/?f=%20%5Crm%20Numbers%20%3D%204%20%5C%20and%20%5C%20-3.)
Step-by-step explanation:
Given :-
The sum of two numbers is 1 .
The product of the nos . is 12 .
And we need to find out the numbers. So let us take ,
First number be x
Second number be 1-x .
According to first condition :-
![\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}](https://tex.z-dn.net/?f=%5Crm%5Cimplies%201st%20%5C%20number%20%2A%202nd%20%5C%20number%3D%20-12%5C%5C%5C%5C%5Crm%5Cimplies%20x%281-x%29%3D-12%5C%5C%5C%5C%5Crm%5Cimplies%20x%20-%20x%5E2%3D-12%5C%5C%5C%5C%5Crm%5Cimplies%20x%5E2-x-12%3D0%5C%5C%5C%5C%5Crm%5Cimplies%20x%5E2-4x%2B3x-12%3D0%5C%5C%5C%5C%5Crm%5Cimplies%20x%28x-4%29%2B3%28x-4%29%3D0%5C%5C%5C%5C%5Crm%5Cimplies%20%28x-4%29%28x%2B3%29%3D0%5C%5C%5C%5C%5Crm%5Cimplies%5Cboxed%7B%5Cred%7B%5Crm%20x%20%3D%204%20%2C%20-3%20%7D%7D)
Hence the numbers are 4 and -3
Answer:
35
Step-by-step explanation:
6(3)=18
18+20=38
38-3=35
0.49 is the answer because that is <span>the approximate probability</span>
Answer:
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Step-by-step explanation:
the perimeter of the rectangular yard needs to be 20 yards
Perimeter of a rectangle = 2 x ( length + width)
20 = 2 x ( length + width)
( length + width) = 20 /2
( length + width) = 10
The sum of the length and width should equal 10
Possible dimensions that would equal 10 are :
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Answer:
The word "Of" in an equation is interpreted to be multiplication. Also, you must move the decimal two places to the left to change a percent to a decimal.
1. 20 * .12 = 2.4
2. .3 * 70 = 21
3. 300 * .25 = 75 Blue marbles
4. 40 * .35 = $14
