Answer:

            P = 4x  +  10

Step-by-step explanation:

perimeter of a rectangle = 2( width + length )

   P = 2 ( x - 2  +  x + 7 )

   P = 2 ( x + x  +  7 - 2 )

        P = 2 ( 2x +  5 )

            P = 4x  +  10

Use the diagram below: H is the circumcenter of triangle BCD, BC = 18 and HD = 14. Find EH.
just olya [345]

Answer:

  • 10.72

Step-by-step explanation:

<h3>Given</h3>
  • H is the circumcenter of triangle BCD,
  • BC = 18
  • HD = 14
<h3>To find </h3>
  • Length of EH
<h3>Solution</h3>
  • Triangle BHD is isosceles, therefore BH = HD
  • Point E is midpoint of BC, therefore BE = 1/2BC

<u>Using Pythagorean, finding the value of EH:</u>

  • EH = √(BH² - BE²) = √(14² - (18/2)²) = √(196 - 81) = √115 = 10.72

Which equation correctly applies the distributive property?
Step2247 [10]

Answer: Only Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Distributive property states that

a\times (b+c+d)=a\times b+a\times c+a\times d

According to option 'C', we get that

a = 0.5

b = 0.5

c = 0.3

d = 0.2

So, it is written as

0.5(0.5+0.3+0.2)=0.5\times 0.5+0.5\times 0.3+0.5\times 0.2

Hence, only Option 'C' is correct.

Find the missing angles
7nadin3 [17]

1. 90°

2. 25°

1. A straight line has an angle of 180°, and if one part of it measures 90°, then that means the other part has to measure 90°.

2. Again, a straight line measures 180°, and if one part measures 155°, the other part must measure 25° in order for the entire angle to measure 180°.

Hope this helps, and please consider marking branliest.
