Answer:
x = -1
Explanation:
Step 1: Simplify both sides of the equation.
−2(x+3)=−4(x+1)−4
(−2)(x)+(−2)(3)=(−4)(x)+(−4)(1)+−4(Distribute)
−2x+−6=−4x+−4+−4
−2x−6=(−4x)+(−4+−4)(Combine Like Terms)
−2x−6=−4x+−8
−2x−6=−4x−8
Step 2: Add 4x to both sides.
−2x−6+4x=−4x−8+4x
2x−6=−8
Step 3: Add 6 to both sides.
2x−6+6=−8+6
2x=−2
Step 4: Divide both sides by 2.
2x = -2
/2 /2
x=−1
I hope this helped answer your question! Have a great rest of your day!

Answer:
Distance =√(x₁ - y₁)²+ (x₂ - y₂)² = √97 = 9.85
Step-by-step explanation:
The Matrix X and Y could also be referred to as vectors in Rⁿ dimensions.
if Vector X = ( x₁ , x₂) and Vector Y = (y₁ , y₂)
then, Distance (X-Y) = ||X-Y|| = √(x₁ - y₁)²+ (x₂ - y₂)²
where, x₁ = 8, x₂ = -5 and y₁ = -1 , y₂ = -9
Distance = √(8 - (-1))²+ (-5 - (-9))² = √9² + 4² =√97 = 9.85
Answer:
ok so what part
Step-by-step explanation:
Answer:
II. Longitud, L = 70 metros.
I. Ancho = 55 metros.
Step-by-step explanation:
Deje que la longitud del rectángulo sea L.
Deje que el ancho del rectángulo sea W.
Dados los siguientes datos;
Perímetro del rectángulo = 250 m
Traduciendo el problema verbal a una expresión algebraica, tenemos;
W = L - 15
Matemáticamente, el perímetro de un rectángulo viene dado por la fórmula;
P = 2 (largo + ancho)
250 = 2 (L + L - 15)
250 = 2 (2L - 15)
250 = 4L - 30
4L = 250 + 30
4L = 280
L = 280/4
Longitud, L = 70 m
Para encontrar el ancho;
W = L - 15
W = 70 - 15
Ancho = 55 m
Answer:
16
Step-by-step explanation:
17-9=8
8*2=16
Because had 8 but bought 9 more to where he then had 17 but if you take 8 times 2 then your answer is 16 and that's how many comic books he began with.
Hope this helps
