The scale factor is 2 so you would increase each length by 2
Answer:
A) 24 - 3p
Step-by-step explanation:
Distribute 6 through parenthesis
24 - 12p + 9p
then collect like terms
24 - 3p
I believe there is something wrong with the fourth equation. It shouldn"t be equal the first equation. It should be: -ac = - db
Let's calculate the linear equations of AB & CD
x/(x-b) = (y-a)/y
xy = (x-b)(y-a)
-ax-by+ab=0
y=-ax/b+a
(x+c)/x= y/(y+d)
(x+c)(y+d)=xy
dx+cy+cd=0
y=-dx/c - d
-a/b = -d/c in other words:
-ac = -db (Resembling the fourth equation)
Answer:
x ≈ 10.9
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = = ( multiply both sides by x )
x × sin40° = 7 ( divide both sides by sin40° )
x = ≈ 10.9 ( to the nearest tenth )
1 and 5 are supplementary angles since they form a straight line
