Answer:
The scale factor is 2.
Step-by-step explanation:
Take the vertical sides of the 2 triangles.
Their length is 3 and 6 so the scale factor is 6/3 = 2.
Also we see than the horizontal lines are in the same ratio 4 : 2 = 2:1.
Answer: correct answer is D.
Step-by-step explanation:
Answer:
7x + 4y
Step-by-step explanation:
We have to write an equivalent expression of the given expression in standard form.
The expression is - 5(x - 4y) + 2(6x - 8y)
= -5(x) - 5(- 4y) + 2(6x) + 2(- 8y)
{Applying the distributive property of multiplication}
= - 5x + 20y + 12x - 16y
= (-5x + 12x) + (20y - 16y)
{Separating the x and y terms}
= 7x + 4y (Answer)
[8x-2y]+[3x-4y]
=8x+3x-2y-4y
=11x-6y
So you would use the law of sines so set up the equation sin18/16 = sin72/x (sin 72 being the top angle) and then you cross multiply and solve from there:)
Hope this helps!
