Answer:

1.) -4x+30y 2.) distributive property 3.) -4x+30y, (-0.4(3)+3(2)), 10(-1,2)+10(6), -12+60, =48

Step-by-step explanation:

10(-0.4x+3y)= 10(-0.4x)+10(3y)= -4x+30y

10(-0.4(3)+3(2))

10(-0.4(3))+10(3(2))

10(-1.2)+10(6)

-12+60

= 48

Given: △ABC, E∈ AB m∠ABC=m∠ACE AB=34, AC=20 Find: AE

butalik [34]

Answer:

The length of AE is 11.8 units.

Step-by-step explanation:

Given the triangle ABC, E∈ AB m∠ABC=m∠ACE AB=34, AC=20. we have to find the length of side AE.

In ΔACE and ΔABC

∠A=∠A (Common)

∠ABC=∠ACE (Given)

∴ By AA similarity, ΔACE is similar to ΔABC

Hence by triangle proportionality theorem,

$\frac{CE}{BC}=\frac{AE}{AC}=\frac{AC}{AB}$

⇒ $\frac{AE}{AC}=\frac{AC}{AB}$

⇒ $\frac{AE}{20}=\frac{20}{34}$

⇒ $AE=\frac{20}{34}\times 20=\frac{400}{34}=11.8units$

PLEASE HELP

Answer:

Ok. so let's teach you how to find the angles of a triangle. When you add all three sides, they must equal 180 degrees. Because of this, let's do some math. What is 96+35. Ima pretend you said 131 and so you would be right. Now let's subtract that from 180 degrees. 180-131 is 49 and so x is 49 degrees. Hope this helps!!
