Since the triangles are congruent and m<I is congruent to m<P.
Therefore, 3x + 4 = 72 - x
3x + x = 72 - 4
4x = 68
x = 68/4 = 17
x = 17

What is the monomial if a square of a monomial is: 0.0001*a^8*x^4
Georgia [21]

Answer:

Monomial 0.0001\cdot a^8\cdot x^4 is a square of monomial 0.01\cdot a^4\cdot x^2

Step-by-step explanation:

Given monomial 0.0001\cdot a^8\cdot x^4

Using property (a^m)^n=a^{m\cdot n}, note that

0.0001=(0.01)^2\\ \\a^8=(a^4)^2\\ \\x^4=(x^2)^2

So,

0.0001\cdot a^8\cdot x^4=(0.01)^2\cdot (a^4)^2\cdot (x^2)^2.

Now use property (a\cdot b)^n=a^n\cdot b^n to rewrite the previous expression:

(0.01)^2\cdot (a^4)^2\cdot (x^2)^2=(0.01\cdot a^4\cdot x^2)^2

Hence, monomial 0.0001\cdot a^8\cdot x^4 is a square of monomial 0.01\cdot a^4\cdot x^2

What is the measure of AngleDCF? Three lines extend from point C. The space between line C D and C E is 75 degrees. The space be
gizmo_the_mogwai [7]

Answer:

  ∠DCF = 129°

Step-by-step explanation:

We assume that line CE is between lines CD and CF.

The angle sum theorem applies:

  ∠DCF = ∠DCE +∠ECF

  ∠DCF = 75° +54°

  ∠DCF = 129°

9 -4n+ 3n = 8n + 3 -3
ArbitrLikvidat [17]

Answer:

Answer:

n = 1

Step-by-step explanation:

This equation is just basic alegebra.  First, combine like terms to get

9 - n = 8n.  (Because 3 - 3 = 0, and -4n + 3n = -n.)  Now the equation is much simpiler;  add n to both sides to get 9 = 9n.  Divide 9 by both sides to get that n = 1.  

You can check your answer by plugging 1 in for n.  

9 - 4(1) + 3(1) = 8(1) + 3 - 3

9 - 4 + 3 = 8 + 3 - 3

5 + 3 = 11 - 3

8 = 8

Therefore, n is proven to equal 1.  

Hope this is helpful kid sorry i went very far yesterday hope you can forgive me but Anyways here it is <3
