Answer:
y = 16
Step-by-step explanation:
6y - (6 + 4y) = 26
6y - (6 + 4y) = 2y - 6
2y - 6 = 26
+6 +6
-------------------
2y = 32
/2 /2
-------------------
y = 16
Answer: b) sq. root of 65
use pythagorean theorem to solve
a2+b2=c2
3^2+b^2=5^2
9+b^2=25
b^2=16
b=4
apply to other triangle for second leg
7^2+4^2=c^2
49+16=c^2
65=c^2
sq root of 65= c
Answer:
Hope that this is helpful.
Step-by-step explanation:
-3(2x-1)^2+12x^2
= -3[(2x-1)(2x-1)]+12x^2
=-3[2x(2x-1)-1(2x-1)]+12x^2
=-3(4x^2-2x-2x+1)+12x^2
=-3(4x^2-4x+1)+12x^2
=-12x^2+12x-3+12x^2
=(-12x^2+12x^2) +12x-3
=0+12x-3
=12x-3
5(n-10)=40 is the equation
5n-50=40 solve for n
5n = 90
n =18
hope this helps . give me brainliest id appreciate it !
