=7(3x+2y) taking common 7
The fractions 16/20, 12/15, and 8/10 are equivalent fractions to 4/5.
When writing equivalent fractions, the numerator and denominator should be multiplied or divided by the same number. This is the reason why when these fractions are simplified, they are reduced to the same value.
Let us understand the two ways in which we can make equivalent fractions:
Now, Divide the denominator or numerator by the same number or multiply the denominator and the numerator by the same number.
So, the equivalent fractions for 4/5 are:
(4/5) × (2/2) = (4 × 2) / (5 × 2) = 8/10
(4/5) × (3/3) = (4 × 3) / (5 × 3) = 12/15
(4/5) × (4/4) = (4 × 4) / (5 × 4) = 16/20
After simplifying, 16/20, 12/15, and 8/10 equal 4/5, indicating that they are identical in nature.

Answer:
Area(PART)= 7.5 u^2
Step-by-step explanation:
RT=1 unit
PA=4 units
Distance between T (or R) and PA= 3 units
RT;PA = Bases
T (or R)--> PA= Altitude/Height
Area of trapezoid= Alt(B1+B2)/2
--> 3(1+4)/2
=> 3*5÷2
=15/2
=7.5
Thanks
Let theta = A... Since I got no theta in my phone's keyboard
CotA /cosAsecA
Buh we all know cotA=1/tanA.....which can also be rewritten as cosA/sinA.... (thus the reciprocative Form of sinA/cosA)
SecA=1/cosA
Therefore
1/tanA ÷cosAx1/cosA
1/tanA ÷cosA/cosA
CosA/cosA=1
1/tan A÷1
Hence =cosA/sinA
Therefore the answer would be C.
