-pd - pz = -2z + 59
-pz = -2z + 59 + pd
-pz + 2z = 59 + pd
-z(p - 2) = 59 + pd
-z = 59 + pd over p - 2
z = -59 + pd/p - 2.
Answer: 8g + 1
Step-by-step explanation:
(5g + 4) + 3(g - 1)
5g + 4 + 3g - 3
Bring like terms together
5g + 3g + 4 - 3
Combine like terms
8g + 1
Answer:
4
Step-by-step explanation:
Because 3×4=12
Answer:
2
Step-by-step explanation:
Ok, so if we know how much wire is needed for one outlet, we must figure out how many 18.25s fit into 50 ft of wire.
18.25*2=36.5
18.25*3=54.75 which is over 50 so it cannot possibly be more than 2.
X² + 10x +2 = 0 .Complete the square of (x² + 10x + ??)
We know that (10x) is equal to twice the square root of the 1st (x) by ??
10x = 2.x.(??) and ?? = 5 and its square is 25. Then I have to add 25 and subtract 25 so that not to change the equation:
(x² + 10x + 25) -25 +2 =0
(x+5)² -23
