Factored expression 16m2-9

Mathematics
1 answer:
kirza4 [7]3 years ago

Answer:

The factored form of  16m²-9 = (4m+3)(4m-3)

Step-by-step explanation:

16m²-9

To find the factors of the expression, first you have to find out the perfect square of the terms:

4 is the perfect square of 16

∴4 is the number if multiplied two times wil give the product of 16.

m is the perfect square of m²

3 is the perfect square of 9

Then,

16m2-9 = (4m)² - (3)²

Now apply the perfect square formula:

a²  - b²  = (a+b)(a-b)

Therefore,

(4m)² - (3)² = (4m+3)(4m-3)

Thus the factored form of  16m²-9 = (4m+3)(4m-3) ....

Answer:

The answer is "99.82% and 86.99%".

Step-by-step explanation:

In point a:

=P(X < 45)\\\\= P(Z < \frac{45-29.09}{5.46}) \\\\=P(Z < 2.9139)\\\\=0.9982\\\\=99.82\%

In point b:

=P(X >17)\\\\= P(Z > \frac{17-22.37}{4.77}) \\\\=P(Z > -1.1258)\\\\=0.8699\\\\=86.99\% \\\\

Which reason justifies the following statement?
amid [387]

Answer:

(A) Complements of the same  angle are congruent.

Step-by-step explanation:

Since, ∠CEF is complementary to ∠DCF, therefore

∠CEF+∠DCF=90°                                 (1)

Also, ∠CEG=∠CEF+∠FEG

⇒90°=∠CEF+∠FEG                              (2)

Therefore, from(1) and (2), we get

∠CEF+∠DCF=90°    

∠CEF+∠FEG=90°

Subtracting both the equations, we get

  ∠DCF-∠FEG=0

∠DCF=∠FEG.

Hence, ∠DCF≅∠FEG by the rule: Complements of the same  angle are congruent.
