After factor by grouping $7c^4-4c^3+28c^2-16c$ we get $c(7c-4)(c^2+4)$

Step-by-step explanation:

We need to factor the term:

$7c^4-4c^3+28c^2-16c$

Taking c common:

$7c^4-4c^3+28c^2-16c\\c(7c^3-4c^2+28c-16)$

Now making groups:

$c(7c^3+28c-4c^2-16)$

Now factorizing by groups:

$c(7c^3+28c-4c^2-16)\\=c(7c(c^2+4)-4(c^2+4))\\=c((7c-4)(c^2+4))\\=c(7c-4)(c^2+4)$

So, after factor by grouping $7c^4-4c^3+28c^2-16c$ we get $c(7c-4)(c^2+4)$

2:x and 12:18 a-3, b-4, c-6

nirvana33 [79]

The Corrected Problem is :

2:x and 12:18 identify the value of x that makes each pair of ratios equivalent .

Solution:

If a pair of Ratios are equivalent then we can write

$\frac{2}{x}=\frac{12}{18}\\ \\ \text{Simplify we get}\\ \\ 12x=36\\ \\ \text{Divide both the sides by 12 we get}\ \\ \\ \frac{12x}{12}=\frac{36}{12}\\ \\ x=3\\ \\ \text{Hence the required value of x is 3}\\$

The base of the 37 foot ladder is 9 feet from the wall of a building. will the top of the ladder reach a window ledge 35 feet ab

AnnZ [28]

Answer:

The answer to your question is Yes.

Step-by-step explanation:

The math in this problem is that we need to use the Pythagorean theorem to solve it. Pythagorean theorem is part of trigonometry a branch of Maths.

Data

base = 9 ft

length = 37 ft

height = ?

Pythagorean theorem

c² = a² + b²

length = c

base = a

height = b

37² = 9² + b²

-Solve for b

b² = 37² - 9²

-Simplify

b² = 1369 - 81

b² = 1288

-Result

b = 35.88

-Conclusion

The ladder will reach a height higher than 35 ft.

If BAC = 320°, what is the measure of BC?

melisa1 [442]

Answer:

BC = 40º

BMC = 40º

Step-by-step explanation: Since the measure the major and minor arcs add up to 360º, just subtract 320 from 360 to find BC which is 40º. <BMC is also 40º because the measure of the arc is equal to its corresponding angle.
