Substitution for both equations is (-3,1)
X^2+5^2=7^2
x^2+25=49
(49-25)
x^2=24
sqrt(24)=4.89897948557
Step-by-step explanation:
E
working ;
(3x+2)^2
*Apply Perfect Square Formula : (a+b) =a^2+2ab+b^2
a = 3x,b = 2
(3x)^2 + 3x.2+2^2
finally Answer is:
= 9x^2 + 12x +4
Answer:
k > -26
Step-by-step explanation:
To isolate the k, you subtract 6 from both sides to get k < -26.
