I need help with #11 - #14.

Aleonysh [2.5K]

Answer:

I can get you jump started a bit.

Step-by-step explanation:

So Each of those pairs of figures are Similar.

This means they have equal angle measures but different side lengths.

To find it, we have to make a Proportion:

Example: #11

$\frac{x+1}{3x+1} =\frac{8}{20}$

So let's solve the first one!

$24x+8=20x+20\\4x=12\\x=3$

Easy As Pie!

If you need more help, contact me! :)

Hope this Helps!

P.S. Stay Safe!

Which values of P and Q result in an equation with no solutions?

Ad libitum [116K]

Try this solution/explanation:

way 1:

rule: for an equation where no roots P+Q=0. It means, Px-Qx=0, ⇔ x(P-Q)=0, ⇔ P=Q.

for answer 'D' P=Q=15.

way 2:

rule: if an equation of the line has a form y=kx+b, then y₁||y₂ if k₁=k₂. It means, for y₁=Px-45 || y₂=Qx+75, then P=Q. P=Q, if 'D' answer.

Answer: D
