Answer:
(x + 1)(5x - 3)
Step-by-step explanation:
Given
5x² + 2x - 3
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term, that is
product = 5 × - 3 = - 15 and sum = + 2
The factors are + 5 and - 3
Use these factors to split the x- term
5x² + 5x - 3x - 3 ( factor the first/second and third/fourth terms )
= 5x(x + 1) - 3(x + 1) ← factor out (x + 1) from each term
= (x + 1)(5x - 3) ← in factored form
You need three non-collinear points to name a plane.
Non-collinear means "not on the same straight line". So these three points can't all lie on the same straight line. If three points do lie on the same straight line, then it is impossible to generate a single unique plane.
Answer:
3 unidades de comprimento
Step-by-step explanation:
O perímetro é definido como a soma de todos os lados.
O perímetro de um quadrado de lado 2x é dado por:
O perímetro de um retângulo de comprimento x e largura x² é dado por:
Para que ambos os perímetros sejam iguais:
O valor de x é igual a 3 unidades de comprimento.
Answer:
The actual distance between the two places to the nearest tenth of a kilometer is 63.3 km
Step-by-step explanation:
Here, we want to get the actual distance between two places on a map, given the scale used to draw the map and the distance of both places on the map, in terms of the scale.
The scale used here is 1cm to 11.5km
Since 1cm = 11.5km
then 5.5cm = x km
Thus ; x = 5.5 * 11.5
x = 63.25 km
Our answer in wanted to the nearest tenth of a kilometer so the answer is 63.3 km
