Answer:
Step-by-step explanation:
1st . 1.3^2= 1.69
1.4^2= 1.96
It's not bettween 1.3 & 1.4
2. 1.4^2=1.96
1.5^2= 2.25
it's betteen 1.4 & 1.5
3 . 1.4 & 1.5 so it's eqaul 1.4
Factors of 12 include- 1, 2, 3, 4, 6,
Remember: We have to work from either the LHS or the RHS.
(Left hand side or the Right hand side)
You should already know this:
1.
2.
3.
<span>So, our question is:
</span>
Plug in the first two identities I gave you.
Apply the first identity I said you needed to know on 1/(tan θ). We should get:
Multiply the first fraction by sinθ, on both the numerator and denominator.
Multiply the second fraction by cos<span>θ, on both the numerator and denominator.
</span>
Now, use the third identity I said that you needed to know to simplify the numerator.
LHS = RHS
<span>
Therefore, identity is verified.</span>
Step-by-step explanation:
x−7(x−2)=10x+9−x
Step 1: Simplify both sides of the equation.
x−7(x−2)=10x+9−x
x+(−7)(x)+(−7)(−2)=10x+9+−x(Distribute)
x+−7x+14=10x+9+−x
(x+−7x)+(14)=(10x+−x)+(9)(Combine Like Terms)
−6x+14=9x+9
−6x+14=9x+9
Step 2: Subtract 9x from both sides.
−6x+14−9x=9x+9−9x
−15x+14=9
Step 3: Subtract 14 from both sides.
−15x+14−14=9−14
−15x=−5
Step 4: Divide both sides by -15.
−15x−15=−5−15
x=13
Answer:
x=13
