Answer:

The variables change

Step-by-step explanation:

Since we can't subtract c from -b we multiply both variables by a because the question is telling us to subtract b and c then multiply the awnser by a, but we don't know what b and c is so we just multiply b and c by a. In the end we get ab-ac

Answer:

7 boxes

Step-by-step explanation:

The area of a rectangular prism is given by the formula ...

A = 2(LW +H(L+W))

The amount of wallpaper Carmen needs for one box is found by computing the area of the box.

A = 2(5·6 +7(5+6)) = 2(30 +7·11) = 2(107) = 214 . . . square feet

<h3>All boxes</h3>

Carmen will be using a total of 214x square feet of wallpaper to cover x boxes. She has 1498 ft² available, so can cover ...

1498 ft²/(214 ft²/box) = 7 boxes

Carmen has enough wallpaper to cover 7 storage boxes.

Solve sin2theta=2sinthetacostheta

pashok25 [27]

Answer:

$\sin(2\theta) =2 \sin \theta \cos \theta$ proved

Step-by-step explanation:

Given

$\sin2 \theta=2 \sin\theta cos\theta$

Required

Prove

Proving from left to right.

$\sin(2\theta) = \sin(\theta+\theta)$

In trigonometry

$\sin(A+B) = \sin A \cos B+\sin B \cos A$

When this formula is applied to: $\sin(2\theta) = \sin(\theta+\theta)$

We have:

$\sin(2\theta) = \sin \theta \cos \theta+\sin \theta \cos \theta$

$\sin(2\theta) =2 \sin \theta \cos \theta$
