4x=6x-14

4x-6x=6x-6x-14 (subtract -6x on both sides)

-2x=-14 (divide both sides by -2x)

x=7

$4x=6x-14 \\ 4x+14=6x \\ 14=2x \\ \frac{14}{2}=x \\ \boxed{x=7} \\ \\ Check: \\ 4x=6x-14 \\ 4(7)=6(7)-14 \\ 28=42-14 \\ 28=28 \\ it\ works!$

Answer: 13.96 in²

Step-by-step explanation:

radius (r)

d = 2r

16 = 2r

8 = r

angle in radians (θ)

$\frac{180}{\pi} =\frac{25}{\theta}$

180(θ) = 25(π)

θ = $\frac{25}{180}\pi$

θ = $\frac{5}{36}\pi$

Area (A)

A = $\frac{1}{2}$ r² θ

= $\frac{1}{2}(8)^{2}(\frac{5}{36}\pi)$

= $\frac{40}{9}\pi$

= 13.96

Answer: 12π

Step-by-step explanation:

s = rθ

= 60 $(\frac{\pi }{5})$

= 12π

Answer: 22.440 cm²

Step-by-step explanation:

A = $\frac{1}{2}$ r²θ

= $\frac{1}{2}$ (10)² $(\frac{\pi} {7})$

= $\frac{50}{7}\pi$

= 22.440

Answer: 270°, 630°, -450°, -810°

Step-by-step explanation:

positive: -90 + 360 = 270

270 + 360 = 630

negative: -90 - 360 = -450

-450 - 360 = -810

Answer: $\frac{3\pi} {4}$

Step-by-step explanation:

$\frac{19\pi} {4} - 2\pi$

= $\frac{19\pi} {4} - \frac{8\pi} {4}$

= $\frac{11\pi} {4}$

$\frac{11\pi}{4} - 2\pi$

= $\frac{11\pi} {4} - \frac{8\pi} {4}$

= $\frac{3\pi} {4}$

If you subtract another 2π, you will end up with a negative value. The question asks for the smallest positive value.

12=w−|−7| help me on this

Crank

We first take the absolute value of -7, making 7. This simplifies the equation to 12=w-7. Adding 7 to both sides finds us w=19.

Answer:

See Explanation

Step-by-step explanation:

Given

$\triangle ABC = \triangle DE F$

Required

Which would not prove the similarity

$\triangle ABC = \triangle DE F$ implies that:

The following angles are congruent

$\angle A = \angle D$

$\angle B =\angle E$

$\angle C =\angle F$

And the following lengths are congruent

$AB = DE$

$BC =EF$

$CA = FD$

The options are not clear; so, it's a bit difficult to select the correct option.

Any of the options that is different from the above list of 6 congruent pairs is the answer to your question.
