This is an isosceles triangle, therefore we have two sides with the same length.
This sides are JM and MK; therefore:
JM=MK
JM=9x-18
MK=3x
Therefore:
9x-18=3x
9x-3x=18
6x=18
x=18/6
x=3
Part A:
Answer: x=3
Part B:
JM=9x-18=9(3)-18=27-18=9
Answer: JM=9
Answer:
4x²y² + 20xy² + 25y²
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
a = 2xy ; b = 5y
(2xy +5y)² = (2xy)² + 2*(2xy) * (5y) +(5y)²
= 2²x²y² + 2* 2* 5 * x*y*y + 5²*y²
=4x²y² + 20xy² + 25y²
Answer:yes
Step-by-step explanation:
because 0.89 is a very small number so itd be reasonable for it to be a large number
Answer:
<u>Step-by-step explanation:</u>
The square of the trinomial exists only if (a + b)² = a² + 2ab + b²
