Answer:

1. x =8

2.  x=9

Step-by-step explanation:

Since these figures are parallelograms, the opposite sides are equal.

1.     6 = 2x-10

Add 10 to each side

   6+10 = 2x-10+10

   16 = 2x

Divide  each side by 2

16/2 = 2x/2

 8 =x


2.  x+14 =23

    Subtract 14 from each side

x+14-14 = 23-14

x = 9

The time, in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters
Serhud [2]

Answer:

d=\dfrac{t^2}{a}

Step-by-step explanation:

The time  in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this  equation.

t = va

We need to find the expression for d in terms of t and a.

As velocity = distance/time

t=\dfrac{d}{t}a\\\\t^2=da\\\\d=\dfrac{t^2}{a}

So, the distance d is \dfrac{t^2}{a}.

Aliun [14]
<span>1. Measure the distance the solvent front traveled from the baseline (m1). 2. Measure the distance the reactant b spot traveled (the center of the spot) (m2). 3. To determine the rf, divide (m2/m1). 4. Significant figures- use 2 so the answer should be written to the hundredths place as the spot will not travel farther than the solvent front.</span>
