What is the length of angle EF in the right triangle below

Mathematics
1 answer:
salantis [7]3 years ago
6 0

Answer:

E.  √180

Step-by-step explanation:

Using Pythagoras' theorem

a^2 + b^2 = c^2 (c = hypotenuse, a and b are legs)

a^2 = c^2 - b^2

a^2 = 18^2 - 12^2

a^2 = 324 - 144

a^2 = 180

a = √180

Answer

E.  √180

Need help fast please! Factor by grouping. 6x³ + 24x² -7x -28 =
olchik [2.2K]

Answer:

(x+4)(6x^2 - 7)

Step-by-step explanation:

Focus on the first 2 terms first and on the second 2 terms last:

6x^3 + 24x^2 = 6x^2(x+4)

-7x-28 = -7(x+4)

We see that the factor (x+4) is common to both pairs:  common to the first 2 terms and common to the last 2 terms.

Thus,

6x³ + 24x² -7x -28 = (x+4)(6x^2 - 7(x+4)

Factoring out x+4, we get (6x^2 - 7), and so 6x³ + 24x² -7x -28 in factored form is (x+4)(6x^2 - 7).

Which graph represents this system?<br> 2x-5y=-5<br> y = ² x + 1<br> 5
frosja888 [35]

Answer:

x =  \frac{5(y - 1)}{2}  \\  \\ x =  \frac{y - 1}{2}

Step-by-step explanation:

2x =  - 5 + 5y \\ 2x = 5y - 5 \\ x =  \frac{5y - 5}{2}  \\  \\ y - 1 = 2x \\  \frac{y - 1}{2}  = x
