If a triangle has 3 side one is 12 one is 72 what is the last sude
Answers
this triangle has 3 sides one is 12, lets call this side a²
another side is 72, lets call this side c²
this triangle must follow Pythagoras therom if it is right angled, that is a²+b²=c²
where a and b are the two shorter sides and c is the longest side (called the hypotenuse) opposite the right angle
to find the last side you do 72² - 12² = 5040
but it is the square root of 5040 which is 70.99 (two decimal places) if you want it in decimal form, if you want it in surd form it is √5040
The 3rd side can be ANY length between 60 and 84. You can't
solve a triangle if you only know 2 sides of it.

What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Two linear equations in two variables are:
2x + ky = 3 and
kx + 8y = 7
As we know the condition for the lines to intersect or have unique solutions:
2/k ≠ k/8
After cross multiplication:
k² ≠ 16
k ≠ ±4
The values of k can be anything except 4 and - 4
Thus, the lines 2x + ky = 3 and kx + 8y = 7 intersect for all values of k except 4 and -4 the answer is R - {4, -4}.

Answer:
ky=3-2x
y=(3-2x)/k
y=(7-kx)/8
(3-2x)/k=(7-kx)/8
8(3-2x)=(7-kx)k
24-16x=7k-k*kx
24=7k-kkx+16x
24+7k=kkx+16x
24+7k=x(k^2+16)

If 2x=(360/4) then the The value of x is 45.
To solve for x, we can simplify the equation step by step:
Step 1: Simplify the right side of the equation:
360/4 = 90
Step 2: Substitute the value of (360/4) into the equation:
2x = 90
Step 3: Isolate x by dividing both sides of the equation by 2:
x = 90/2
x = 45
So, the value of x is 45.

Let x = each 500 grams
Cooking time = 30x + 20
2.5 kg = 2500 grams
2500 / 5 = 5
X = 5
We put this in to the equation,
30*5 + 20 = 170 minutes
It will take 170 minutes to cook a joint of meat weighing 2.5 kilograms

n^2-3n-3=1
Subtracting 1, we see that:
n^2-3n-4=0
Factoring, we have:
(n-4)(n+1)=0
Therefore, 4 and -1 are the solutions, since if either n-4 or n+1 is zero, the whole expression is zero.
