Step-by-step explanation:

<h3>1. x² + 4 = (x+2)² </h3>

<h3> : x² + 4 = x² + 4 (Yes)</h3>

<h3>2. (2x+6)²= 4(x+3)²</h3>

<h3> : 4x²+36 = 4x² + 36 ( Yes)</h3>

<h3>3. (x-3)(x-3)= (x-9)² (NO)</h3>

<h3>beacause , True statement is</h3><h3> (x+3)(x-3)= (x-9)²</h3>

<h3>4. x²-10x+25 = (x-5)(x+5) (No)</h3>

<h3> : x²-2x+y² = (a-b)(a+b) </h3>

<h3>Therefore, its not true statement!</h3>

A stack of 500 pieces of paper is 1.015 inches tall. What is an appropriate estimate for the thickness of each piece of paper?
Vinvika [58]

Answer: 0.002 inches

Step-by-step explanation:

A stack of 500 pieces of paper is 1.015 inches tall. The appropriate estimate for the thickness of each piece of paper would be gotten by dividing 1.015 by 500. This will be:

= 1.015 / 500

= 0.00203

= 0.002 inches

Find the measure for LQR.
Charra [1.4K]

Answer:

Option A

m\angle LQR=126^o

Step-by-step explanation:

step 1

Find the value of b

we know that

m\angle MQR=m\angle LQX ----> by vertical angles

substitute the given values

(-3b+63)^o=(90-12b)^o

solve for b

12b-3b=90-63\\9b=27\\b=3

step 2

Find the measure of angle LQR

we know that

m\angle LQR+m\angle MQR=180^o ---> by supplementary angles (form a linear pair)

m\angle MQR=(-3b+63)^o

substitute the value of b

m\angle MQR=(-3(3)+63)=54^o

substitute in the expression above

m\angle LQR+54^o=180^o

m\angle LQR=180^o-54^o=126^o
