PLEASE HELP ME I AM FRUSTERATED SOMEONE PLEASE ANSWER THANK U ! I am crying trying cause no one seems to help me please someone help me thank u! THE QUESTION :find the expression that is NOT equivalent ,for the problems 9-16 below

Answers

First of all, don't cry. Second of all, try to post a clearer picture because it was a bit tough to see. Third of all, here are the answers:

In row 9, S is wrong because it is 27x+24y, it should be 36x+24y
In row 10, A is wrong because it is 4+20x, it should be 20x
In row 11, G is wrong because it is 15ab, it should be 10a+5b
In row 12, I is wrong because it is 15x+6y, it should be 15x+10y
In row 13, O is wrong because it is 22a+6, it should be 28a
In row 14, T is wrong because it is 14x, it should be 22x
In row 15, K is wrong because it is 15x+y, it should be 15x+3y
In row 16, T is wrong because it is 14n+84m, it should be 12m+14n

Also on another note, this might be intimidating but it is mostly adding/multiplication of variables. So if you don't know them, you might want to double check that you know how to handle variables in the future;)

Answer:

Answer: Good thing you provided the image!

Working down the columns:

C base= 2

D base = 4

C height =3

D height = 2

C area = bh = 8

D area = bh = 8

Step-by-step explanation:

Try thinking about drawing a rectangle around the entire image of C and D, connecting each of the corners (sort of like what is being done for B) and then you can perceive the b and h.

The trick to D is to turn your head 90 degrees (or sideways) so you can see those 4 boxes as the base.

Mary is three times older than seth is. if their ages total 76, how old is mary. Please answer ASAP

Answers

Mary = 3x

Seth = X

If we know that Mary is three times older than Seth, we can set this up into an equation.

3x + x = 76

Now, we can simplify on the left side by adding the Xs together.

4x = 76

X = 19

Therefore, Seth is 19 years old and Mary is 57 years old.

In the diagram below, DE and Ef are tangent to o. Which expression gives
the measure of DEF?

Answers

The expression which gives the measure of DEF, in the diagram where, DE and Ef are tangent to circle o is 1/2(236-124) degrees.

What is the theorem of two tangents from external point?

When the two tangent are drawn to a circle from an exterior point then according to this theorem-

The length of these two tangents is equal.

Both the tangents subtend equal angle at the center of the circle.
The angle between the two tangent is bisect by the line joining to the exterior point and the center.

In the diagram below, DE and EF are tangent to o. In the diagram half of the difference of the arc GF and DF is equal to the angle of the measure of DEF. Thus,

$\angle DE F=(1)/(2)(GF-DF)\n\angle DE F=(1)/(2)(236-124)$
