Answer:

B. $y(4+z)$

Step-by-step explanation:

We are given that an expression

$y\cdot 4+y\cdot z$

We have to rewrite the expression.

To rewrite the expression we will take common y from given two terms in the expression.

$y\cdot 4+y\cdot z$ (given )

Taking common out y from two given terms in the expression

$y(4+z)$

Therefore, the expression can be written as

$y(4+z)$

Hence, the option B is true.

B. $y(4+z)$

Slove for x 4 ( 4x+15)=24

Advocard [28]

Answer:

x=-9/4

Step-by-step explanation:

4(4x+15)=24 - divide both sides

4x+15=6 - move constant to the right

4x=6-15 -solve for the difference

4x=-9 - divide both sides

Solve the following equation for 0° ≤ θ < 360°. Use the "^" key on the keyboard to indicate an exponent. For example, sin2x w

never [62]

Answer-

$\boxed{\boxed{x=90^{\circ},270^{\circ}}}$

Solution-

The given equation-

$\Rightarrow 2\sin^2 x-\cos^2 x-2=0$

$\sin^2 x+\cos^2 x=1\ \ \Rightarrow \cos^2 x=1-\sin^2 x$

Putting this,

$\Rightarrow 2\sin^2 x-(1-\sin^2 x)-2=0$

$\Rightarrow 2\sin^2 x-1+\sin^2 x-2=0$

$\Rightarrow 3\sin^2 x-3=0$

$\Rightarrow 3\sin^2 x=3$

$\Rightarrow \sin^2 x=1$

$\Rightarrow \sin x=\sqrt1$

$\Rightarrow \sin x=\pm 1$

$\Rightarrow \sin x=1,\ \sin x=-1$

$\Rightarrow x=\sin^{-1}(1),\ x=\sin^{-1}(-1)$

$\Rightarrow x=90^{\circ}+n360^{\circ},\ x=270^{\circ}+n360^{\circ}$

Where n=0, 1, 2, ......

As given 0° ≤ x < 360°, so putting n = 0

$\Rightarrow x=90^{\circ},\ x=270^{\circ}$
