Answer:

\frac{BC}{AD} = \frac{KL}{JM}

Step-by-step explanation:

It is given that ABCD ~ JKLM.

When two polygons are in similar, their respective sides are in proportion as well.

We need to include BC and JM.

BC is similar to KL of the other figure, whereas JM is similar to AD as well.

Therefore,

\frac{BC}{AD} = \frac{KL}{JM}

Y=2(x+1)^2 has how many real roots
oee [108]

The equation y= 2(x+1)^2 has one real root and that is x=-1.

What is real roots of the equation?

    We are aware that when we resolve a linear or quadratic equation, we always arrive at the value variable of the equation, or, to put it another way, we always locate the equation's solution. This "solution" is what we refer to as the real roots. For instance, when the equation X^2-7x+12=0 is solved, the actual roots are 3 and 4.

Here given,

=> y = 2(x+1)^2

Take y=0 then,

=> 2(x+1)^2=0

=> (x+1)^2=0

=>(x+1)=0

=> x=-1

Hence the given equation has one real root and that is x=-1.

The sum of two numbers is 87. if three times the smaller number is subtracted from the larger number the result is seven. find t
Stolb23 [73]
\left \{ {{a+b=87} \atop {a-3b=7}} \right.



a-3b=7
a=7+3b

a+b=87
(7+3b)+b=87
7+4b=87
4b=87-7
4b=80
b=20

a=7+3b
a=7+3*20
a=7+60
a=67
