Answer:
3.6 cm
Step-by-step explanation:
<u>Triangle Proportionality Theorem</u>
BD : DE = BA : AC
⇒ 6 : 10 = BA : 16
⇒ 
⇒ 
⇒ BA = 9.6
AD = BA - BD
⇒ AD = 9.6 - 6 = 3.6 cm
A I think is the right answer
You distribute the 30x to the equation in parenthesis
So basically you are doing (30x*x)+(30x*-3)
So you get 30x^2-90x
Hope this helps!
Answer:
The answer would be (-2, -5)
Step-by-step explanation:
3x - 8y= 34
2(7x + 4y = -34)
3x - 8y=34
14x + 8y= -68
----------------------
17x= -34 divided by 17
x = -2
3(-2) -8y= 34
-6 -8y =34 add 6
-8y= 40 divide by -8
y = -5
if you want to check the answer replacing -2 for x and -5 for y
7(-2) + 4(-5)= -34
-14 + (-20) = -34
-34 = -34
I hope this help sorry I'm not good explaining
