Answer:
x=2 and y=7
Step-by-step explanation:
Let x and be the unknown numbers.
By the condition given in the question the first equation is

And the second equation is
x-y=-5
By solving the first and second equations,we get the answer as
x=2 and y=7
Answer:
The length of CD is 8 units
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
we know that
According to the Right Triangle Altitude Theorem,
substitute the given values
solve the quadratic equation by graphing
The solution is x=8 or x=-6
see the attached figure N 2
Discard the negative length.
therefore
The length of CD is 8 units
Answer: true
Step-by-step explanation:
since the triangles are similar the sides are proportional
Answer:
x=12 pls give brainliest
Step-by-step explanation:
The first one is like 5x5x5x5 which is 625 multiplied by 3x3 which is 9 and together the product will be 5,625.
The second one is 5-4 which is 1-3 which is -2 - 2 = -4 - 1 which is -5 so it’s not it because it’s the opposite of the number we need to find.
The third one is kind of messed up because there’s no such thing as 5.4.3 so sorry I can’t do that one.
The fourth one is 15 because you basically add the numbers up.
And the fifth is not 5. It’s 5.1 so that’s not it either.
So I’m sorry I can’t find the answer but at least I have you some background :/
