Hello:
let : f(x) = <span>x3 − 6x2 + kx + 10
</span><span>If (x + 2) is a factor of x3 − 6x2 + kx + 10 : f(-2) = 0
(-2)^3-6(-2)² +k(-2)+10=0
-8 -24-2k +10 = 0
-2k =8+24-10
-2k = 22
k = -11</span>
-1.825. you subtract 16.2 from 1.6. then divide that number by 8
Answer:
that should be how you would solve those questions..
Answer:
-13
Step-by-step explanation:
(7−15−3+5−7)⋅1
Subtract 15 from 7 to get −8.
(−8−3+5−7)×1
Subtract 3 from −8 to get −11.
(−11+5−7)×1
Add −11 and 5 to get −6.
(−6−7)×1
Subtract 7 from −6 to get −13.
−13
