When the X term is one, and doesn't have a leading coefficient, then you can factor it using the box and diamond method. look up videos on Khan Academy of the box and diamond method for solving trinomials. For number 9, you have a difference of squares. That means you can factor to just 2 terms. (x+4)(x-4) this works because 16 has an easy square root, and the sign in between is a negative(difference)

Answer:

The value of t is 1.75 years.

Step-by-step explanation:

Given that simple interest formula is I = (P×R×T)/100. So you have to substitute the following values into the formula :

$i = \frac{prt}{100}$

$let \: i = 350,p = 2400,r = \frac{25}{3}$

$350 = \frac{2400 \times \frac{25}{3} \times t }{100}$

$350 = \frac{20000t}{100}$

$350 \times 100 = 20000t$

$20000t = 35000$

$t = 35000 \div 20000$

$t = 35 \div 20$

$t = 1.75 \: years$

Please help me answer this with an explanation

Nata [24]

You need to find the slope first. (-9,-4). (3,4)

-4-4= -8
-9-3 =-12. Slope is -8/-12 or 8/12 or 2/3

Perpendicular is the negative reciprocal. Or flip over the 2/3 and make it negative.

The answer is - 3/2

Margarita [4]

Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,

$1-\frac{2}{5}=\frac{5-2}{5}=\frac{3}{5}$
