Answer:
x= 4, -7
Step-by-step explanation:
x^2+3x-28
x^2 multipled by -28 = -28
Which two numbers add up to 3 and multiply to -28?
-4 and 7
-4 + 7 = 3
-4 x 7 = -28
so
(x−4)(x+7)=0
4-4=0
-7+7=0
Hilda's bank balance will remain above $395 fewer than 14 weeks.
The information provided in the question can be modelled into an equation: Required balance = amount she has in her account - (amount by which balance changes x number of weeks)
$395 = $550 - ($82.50t)
We are to determine the value of t. In order to determine the value of t, take the following steps:
Combine similar terms
$82.50t = $1550 - $395
Add similar terms
$82.50t = $1155
Divide both sides of the equation by 82.50
t = 14 weeks

it is about 20 percent of earths water is in the indian ocean
1.) 2 sides are already gonna be 13 so you already have 26 is you add up both those sides. 13+13=26
2.)Subtract 26 from 46 to get the sum of both the widths added together.
46-26=20
3.)Divide 20 by 2 so that you can get the width on one side of the rectangle. 20 / 2 = 10
4.) The width of the rectangle above is 10
I hope this helps :)
