Answer:b,e,f
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
Using the Pythagorean theorem where c = 13, and b = 5, we get (a = x):

Solving for a:


With all due thinking...
I think a Diamond shape will befit your answer. So; The real answer is "Rhomboid"
The reason is that...
A rhomboid has four parallel sides. The opposite sides are equal, but the corners do not form right angles. Think of a rectangle that is slanted(a.k.a diamond) Thats what a Rhomboid is...
A parallelogram that dosent have equal sides is not a rhombus; and which dosent have Right angles are not rectangles and hence cannot be aquares either.
So in all Way a Rhomboid will mark the answer for your question.
Hope it helps..

Answer:

Step-by-step explanation:
Given expression:

There are several ways this problem can be approached, and therefore many different answers. The goal is to reduce the given expression to a simple product of two terms in x, set that to the given form 3a⋅7b then solve for a and b.

Cancel the common factors 3 and 7:


Separate the fraction:




Now equate the simplified expression to the given form:

Therefore:

However, we could also separate them as:

Another way of writing them would be to go back a few steps and separate the fraction in x terms differently:

Therefore, this would give us:

As the given expression reduces to x⁵, we can separate the x term in any way we like, so long as the coefficient of a is ¹/₃ and the coefficient of b is ¹/₇. Therefore, there are many possible answers.
