Given:

2(x + 5)-7= 3(x - 2)

To Find:

• Value of x

Solution:

⇒ 2(x + 5)-7= 3(x - 2)

⇒ 2x+10-7= 3x - 6

Rearranging the like terms,

⇒ 3x-2x = 10 + 6-7

⇒x=16-7

⇒x=9

Verification:

⇒ 2(x + 5)-7= 3(x - 2)

Putting x = 9,

⇒2(9+5)-7= 3(9 - 2)

2(14)-7= 3(7)

⇒28-7=21

⇒ 21 = 21

→ LHS = RHS

Im not so sure about this. I need help making a proof that is 9 steps long. (See image)

Leona [35]

Step-by-step explanation:

Not entirely sure, but I believe something like this:

∠1 + ∠2 = 180° since they are a linear pair;

Since ∠1 = ∠2, we can say:

∠1 + ∠1 = 180°

2(∠1) = 180°

∠1 = 90°

And since:

∠1 = ∠2

∠2 = 90°

So the angle between t and s is 90°;

An angle of 90° means t and s are perpendicular (⊥)

Answer:

A. $\cos \: x - 4 \: \cos \: x \: { \sin}^{2}x$ (first option)

Step-by-step explanation:

➡️ $\cos(x + 2x)$

➡️ $\cos \: x \: { \cos}^{2} x - \sin \: x \: { \sin }^{2} x$

➡️ $\cos \: x(1 - 2 \sin^{2}x) - \sin \: x \times 2 \sin(x) \cos(x)$

➡️ $\cos(x) - 2 \sin^{2} x \cos(x) - 2 \sin^{2} x \cos(x)$

➡️ $\cos(x) - 4 \cos(x) \sin^{2} x$
