Find the distance of (-7,-5) and (-3,4) round to the nearest tenth

Luba_88 [7]

Answer:

7.2 units

Step-by-step explanation:

Distance² = (Change in y)² + (Change in x)²

Distance² = (4 - -5)² + (-3 - -7)²

Distance² = 36 + 16

Distance² = 52

Distance = 7.211102551

Rounding off the answer to nearest tenth gives 7.2 units

The perimeter of a rectangle is 20xm. the length is 6cm longer than the width. what are the length and width of the rectangle?

aleksley [76]

Let width be x

length= 6+x

p=2(l+w)
20=2(6+x+x)
10=2x+6
10-6=2x
4=2x
x=4/2
x=2

Therefore the width is 2 cm and length is (6+2)= 8 cm

Hope I helped :)

What is the factored form of x2 – x – 2? (x – 2)(x 1) (x 2)(x 1) (x – 2)(x – 1) (x 2)(x – 1)

Alexxx [7]

A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

The factored form of the quadratic equation can be done in the following manner,

$x^2-x-2\\\\= x^2-2x+x-2\\\\=x(x-2)+(x-2)\\\\=(x+1)(x-2)$

Thus, the factored form of the quadratic equation x²-x-2 is (x+1)(x-2).
