Ju Chan solved the previous question by finding the expression 4(-15). Which addition problem would give the same result? Choose

Umnica [9.8K]

Answer:

C. (-1)(15+15+15+15)

D. (-15)+(-15)+(-15)+(-15)

Step-by-step explanation:

The original expression: 4(-15)=-60

Let's try choice A: 15+15+15+15=60(not a negative number, so does not work)

Let's try choice B: 4+4+4+4=16(nowhere near -60)no

Let's try choice C: (-1)(15+15+15+15)=(-1)(60)=-60--yes

Let's try choice D: (-15)+(-15)+(-15)+(-15)=-60--yes

Only choices C and D work.

Which of the following would be an acceptable first step in simplifying the expression tanx/1+ secx

djverab [1.8K]

The acceptable first step in simplifying the expression $\mathbf{\frac{tan\ x}{1 + sec\ x}}$ is (a) $\mathbf{\frac{tan\ x(1 - sec\ x)}{(1 + sec\ x)(1 - sec\ x)}}$

The expression is given as:

$\mathbf{\frac{tan\ x}{1 + sec\ x}}$

To change the form of the expression, we simply perform several arithmetic operations on it.

Start by multiplying the expression by 1/1

$\mathbf{\frac{tan\ x}{1 + sec\ x} = \frac{tan\ x}{1 + sec\ x} \times \frac 11}$

Express 1 /1 as (1 - sec x)/(1 - sec x)

$\mathbf{\frac{tan\ x}{1 + sec\ x} = \frac{tan\ x}{1 + sec\ x} \times \frac{1 - sec\ x}{1 - sec\ x}}$

Rewrite the above expression as follows:

$\mathbf{\frac{tan\ x}{1 + sec\ x} = \frac{tan\ x(1 - sec\ x)}{(1 + sec\ x)(1 - sec\ x)}}$

Hence, the acceptable first step is (a)
