Answer:
n = -4
Step-by-step explanation:
−5(n+3)=6(n+4)+5
Step 1: Simplify both sides of the equation.
−5(n+3)=6(n+4)+5
(−5)(n)+(−5)(3)=(6)(n)+(6)(4)+5(Distribute)
−5n+−15=6n+24+5
−5n−15=(6n)+(24+5)(Combine Like Terms)
−5n−15=6n+29
−5n−15=6n+29
Step 2: Subtract 6n from both sides.
−5n−15−6n=6n+29−6n
−11n−15=29
Step 3: Add 15 to both sides.
−11n−15+15=29+15
−11n=44
Step 4: Divide both sides by -11.
−11n
−11
=
44
−11
n=−4
Step-by-step explanation:
(Ax² + Bx + C)²
= (Ax² + Bx + C)(Ax² + Bx + C)
= Ax⁴ + 2ABx³ + 2ACx² + 2BCx + C².
By Comparing Coefficients, we have:
A = 1
2AB = 6
2AC = 7
2BC = a
C² = b
Solving them we get A = 1, B = 3 and C = 3.5.
Therefore a = 2BC = 2(3)(3.5) = 21,
b = C² = (3.5)² = 12.25.
Answer:
12
Because:
30 is to 25 as x is to 10.
As an equation: 30/25 = x/10
Do this equation by: look at image
