Answer:
The quadratic equation is x^2 -12x -120 = 0
where x represents the length of the field
Step-by-step explanation:
We want to make an expression in terms of a quadratic equation;
Let the length of the field be x mm , then the width will be (x-12) mm
Mathematically , the area of the field will be L * B
Thus;
x * (x-12) = 120
That gives;
x^2 -12x = 120
x^2 -12x -120 = 0
First of all, i will change 3/8 into decimal which equal 0.375. Then,
(36.4÷1.6)-(0.375×1.5)
=22.75-0.5625
=22.1875. Hope it help!
Let x = the first number
x+1 = the second number
The sum of our two numbers is therefore: x + (x+1)
When you subtract 13 from the above you get 18 left over.
So our equation is:
x + (x+1) - 13 = 18
Now we can just solve for x:
x + (x+1) = 31
2x + 1 = 31
2x = 30
x = 15
So our first number is 15 and our second number must be 16.
Answer:
B. 24
Step-by-step explanation:
To find this, use Pythagorean Theorem
a^2+b^2=c^2
a is 10, and c is 26. We know 26 is the hypotenuse because it is opposite the right angle
10^2=b^2=26^2
100+b^2=676
Subtract 100 on both sides
b^2=576
Take the square root of both sides
b=24
Hope this helps! :)
