Answer:

Mya wrote two expressions that are not equivalent

Step-by-step explanation:

45 +72 does not equal to 9(5+9)

9(5+9) = 45 + 81

Answer:

D

Step-by-step explanation:

I dislike these kinds of questions. I could argue either of 2 answers - b and d.

b says that her error was that she wrote two expressions that are not equivalent and that is true. She did not write equivalent expressions.

d says she didn't use a common factor to both terms and that is true.

The actual answer is that she made a silly error which we all often do.

8 * 9 is 72

so the distributive property should be

9(5 + 8)

So, what's the answer? I would pick D, but hold your nose when you enter it.

The sum of 48 and itself its half and half of the hal is added to 18​
hammer [34]

Answer:

150

Step-by-step explanation:

We are carrying out Addition

a) The sum of 48 and itself

= 48 + 48 = 96

b) Its half and half of the half

96 + (1/2 × 48) + (1/2 ×( 1/2 × 48)

= 96 + 24 +(1/2 × 24)

= 96 + 24 + 12

= 132

c) is added to 18

= 132 + 18

= 150

Therefore, the sum of 48 and itself, its half and half of the half is added to 18 is 150

Circle A and circle B are congruent. CD is a chord of both circles. If AB = 8 ft and CD = 6 ft, how long is a radius?
bazaltina [42]

Let us say that the intersection point of lines AB and CD is called point E. The lines AB and CD are perpendicular to each other which also means that the triangle CEB is a right triangle.

Where the line CB is the radius of the circle while the side lengths are half of the whole line segment:

EB = 0.5 AB = 0.5 (8 ft) = 4 ft

CE = 0.5 CD = 0.5 (6 ft) = 3 ft

Now using the hypotenuse formula since the triangle is right triangle, we can find for the radius or line CB:

CB^2 = EB^2 + CE^2

CB^2 = (4 ft)^2 + (3 ft)^2

CB^2 = 16 ft^2 + 9 ft^2

CB^2 = 25 ft^2

<span>CB = 5 ft = radius</span>
