Answer:

x=8, x=4

Step-by-step explanation:

Add 4 to both sides

$(x-6)^2=4$

Square root

$(x-6)= \sqrt{4}$

x - 6 = ±2

x = 8

OR x = 4

So, x=8 or x=4

PLEASE HELP!!!

How do you calculate it? You start by expressing the density in the units you have. Then you multiply by appropriate conversion factors to get to the units you want. Treat units as though they were any other variable. A value cancels that appears in both the numerator and denominator of a fraction.

$\dfrac{56.15\,kg}{0.222\,hh}\cdot \dfrac{1000\,g}{1\,kg}\cdot \dfrac{1\,pw}{1.55\,g}\cdot \dfrac{1\,hh}{238.5\,L}\cdot \dfrac{9.091\,L}{1\,pk}\\\\=\dfrac{56.15\cdot 1000\cdot 9.091\,pw}{0.222\cdot 1.55\cdot 238.5\,pk}\\\\ \approx6220\,\frac{pw}{pk}$

Find y when x= -3 for y=2/3 x

marusya05 [52]

Answer:

y = - 2

Step-by-step explanation:

$y = \frac{2}{3} x \\ \\ plug \: x = - 3 \\ \\ y = \frac{2}{ \cancel3} \times ( \cancel{ - 3}) \: \: \red{ \bold{- 1}}\\ \\ y = 2( - 1) \\ \\ y = - 2$

Answer: v = u= $2 \sqrt{2}$

Step-by-step explanation:

v= cos45 * 4= $2 \sqrt{2}$

- Apply Pythagorean theorem

$4^{2}$ = $(2\sqrt{2}) ^{2} + u^{2}$

We have u = $2 \sqrt{2}$

Find the tangents of the acute angles in the right triangle. Write each answer as a fraction. WILL MAKE BRAINLIEST!!

patriot [66]

Answers:

tan(G) = 2
tan(H) = 1/2

=======================================

Explanation:

Recall that tangent is the ratio of opposite over adjacent

tan(angle) = opposite/adjacent

So for reference angle G, we say,

tan(G) = JH/GJ = 2/1 = 2

We'll treat tan(H) in a similar fashion, but the opposite and adjacent sides swap roles. That means we'll apply the reciprocal to the result above to get 1/2 for tan(H)

-----------

So we have this interesting property where

tan(G)*tan(H) = 2*(1/2) = 1

In general,

tan(A)*tan(B) = 1 if and only if A+B = 90 degrees

-----------

Side note: The side sqrt(5) isn't used at all.
