Answer:45 * t = 2.5 * (1-t)...the equation will have one solution.

Step-by-step explanation:

For this case, the first thing you should know is:

d: v * t

Where,

d: distance

v: speed

t: time

To go to school by bus we have:

d = 45 * t

To return from school we have:

d = 2.5 * (1-t)

how the distance is the same:45 * t = 2.5 * (1-t)

If angle I is congruent to angle K, find JK.

Rudiy27

Using Isosceles triangle theorem we can determine that JI = JK
Thus
5x + 4 = 2x+7
3x = 3
x=1
Plug it back into the eqution for JK
2(1) + 7 = JK
9 = JK

Find the zeros of the following

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

13 ) Go...

$f(x) = {x}^{2} - 2x$

$0 = {x}^{2} - 2x$

${x}^{2} - 2x = 0$

Factor x

$x(x - 2) = 0$

$x = 0 \: \: \: or \: \: \: x - 2 = 0$

$x = 0 \: \: \: \: or \: \: \: \: x = 2$

These are the zeroes.

14 ) Go...

$f(x) = {x}^{3} + 9x + 11x - 21$

$0 = {x}^{3} + 9 {x}^{2} + 11x - 21$

${x}^{3} + 9 {x}^{2} + 11x - 21 = 0$

$(x - 1)(x + 3)(x + 7) = 0$

$x - 1 = 0 \: \: or \: \: x + 3 = 0 \: \: or \: \: x + 7 = 0 \\$

$x = 1 \: \: \: or \: \: \: x = - 3 \: \: \: or \: \: \: x = - 7 \\$

These are the zeroes.

HELP!

erastova [34]

Answer:

98 feet

Step-by-step explanation:

If it is similar that means the side lengths are scaled by a scale factor.

The original garage is 30 feet wide, this one is 35 feet. To find the scale factor, 35 / 30 = 1 $\frac{1}{6}$ . Multiply 12 by the scale factor and you get 14 feet as the length. To find the amount of rope to rope off the area, you find the perimeter. Perimter is 2 * length + 2 * width.

14 * 2 + 35 * 2 = 98
