Answer:

55,98,27

Step-by-step explanation:

To solve for the angles we must first find y with this equation

3y+5+2y-7=153

We can simplify this

5y-2=153

153+2=155

155/5=31

y=31

We now know y and can plug it into the angles

<A=2y-7

2(31)-7

62-7

<A=55

<B=3y+5

3(31)+5

93+5

<B=98

Now time for the last angle

Since angle BCA and DCB are next to each other they add up to 180

153+x=180

180-153=27

x=27

<BCA=27

4^-2 x 7^-2 equivalent expression

Savatey [412]

Answer:

Not sure exactly which equivalent expression you are looking for but my goal would be to write it without the negative exponent.

$\frac{1}{28^2}$

Step-by-step explanation:

They have the same exponent and it is multiplication.

There is a law of exponent that says $(a \cdot b)^x=a^x \cdot b^x$ .

So we have $4^{-2} \cdot 7^{-2}$ equals $(4 \cdot 7)^{-2}$ .

Let's simplify (4*7)^(-2).

Since 4*7=28, we can say $(4*7)^{-2}=(28)^{-2}$ .

Some people really hate that negative exponent. All that - in the exponent means is reciprocal. So $28^{-2}=\frac{1}{28^2}$ .

you do change in y divided by change in x
