Answer:

choice 1) 0, -4/5

Step-by-step explanation:

1/(t² + t) = 1/t - 5

multiply both sides of the equation by (t² + t):

1 = (t² + t)/t - 5t² - 5t

1 = t + 1 - 5t² -5t

-5t² - 4t = 0

t(-5t - 4) = 0

t = 0

-5t = 4

divide both sides by -5:

t = -4/5

Serhud [2]

Answer:

6) 24+4x

7) -24x+32

8) -21+42x

9)-24x-12

10) 72- 18x

Step-by-step explanation:

for each problem, you need to distribute the single variable to the parenthesis for the final answer. For example, 3 (4x-25) > 3 x 4x = 12x > 3x-25 = -75 now you put both answers together making it 12x-75

Find the value of x.<br> Round answer to nearest tenth.

Montano1993 [528]

Answer:

The value of x is 12.1

Step-by-step explanation:

To find the value of x, we will just apply the formula of trigonometric ratio;

SOH CAH TOA

sin Ф = opposite/ hypotenuse

cos Ф = adjacent / hypotenuse

tan Ф = opposite / adjacent

From the diagram given, since we are working with angle 48 then opposite is 9 and hypotenuse is x

Ф =48° opposite = 9 and hypotenuse = x

The best formula to use is;

sin Ф = opposite/ hypotenuse

sin 48° = $\frac{9}{x}$

cross-multiply

x sin 48° = 9

Divide both-side by sin 48°

x sin 48° / sin 48° = 9/sin48°

x = 9/sin 48°

=12.11069

x ≈12.1 to the nearest tenth

Therefore the value of x is 12.1
