11.7cm= 117/10cm
and
15.4cm=154/10
area= length * breadth
= 117/10*154/10
= 18018/100
=180.18cm square
Answer:
C
Step-by-step explanation:
Since they are pythagorian triplets, ABC is a right angled triangle at the angle between the arc 3 and arc 4. Theta is the angle opposite to 3 and hence tan(theta)=3/4
Question # 17 Solution
Answer:
Step-by-step Explanation:
The given expression
And we have to solve for x₁
So,
Lets solve for x₁.
Multiply both sides by x₂ - x₁
Divide both sides by -m
Therefore,
Question # 23 Solution
Answer:
Step-by-step Explanation:
The given expression
And we have to solve for n
So,
Let's solve for n.
Multiply both sides by b.
Factor out n.
Divide both sides by -b + x.
Therefore,

Answer: first one =109360044xy−36453348x−2, 2nd,=3037778998,last one,=1968480790
Step-by-step explanation:Evaluate for x=3x,y=6y−2
33x(2025186)(6y−2)−2
33x(2025186)(6y−2)−2
=109360044xy−36453348x−2
Evaluate for x=20,y=25
(3)(20)(2025186)(25)−2
(3)(20)(2025186)(25)−2
=3037778998
because 18 is by itself i just did Evaluate for x=18,y=18
(3)(18)(2025186)(18)−2
(3)(18)(2025186)(18)−2
=1968480790
