If you would like to find 2 numbers which you can add up to get 24 and multiply to get -25, you can calculate this using the following steps:

a + b = 24 ... b = 24 - a
a * b = -25 ... a * (24 - a) = -25 ... 24 * a - a^2 = -25 ... 0 = a^2 - 24 * a - 25
0 = (a - 25) * (a + 1)
1. a = 25
2. a = -1

b = 24 - a
1. b = 24 - 25 = -1
2. b = 24 - (-1) = 25

The numbers you are looking for are -1 and 25.

-1 and 25 because -1+25=24 and -1x25=-25

Dimas [21]

Answer:

16


Step-by-step explanation:

Area = perpendicular height * base

=  DP * CB

=  √[(2 - -1.2)^2 + (-5 - (-3.4)^ ] *  √[(2 - 0)^2 + (3- -1)^2)]

= √(12.8.) * √(20)

=  16

Find the equation of the line that contains the given point and has the given slope-
mylen [45]

Answer:

y-5 = -3x

or

y = -3x+5

Step-by-step explanation:

We can use the point slope form of the equation

y-y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

y-5 = -3(x-0)

y-5 = -3x

We can change it to slope intercept form y= mx+b by adding 5 to each side

y-5+5 = -3x+5

y = -3x+5

Factor the polynomial.
mrs_skeptik [129]
The coefficients here are 4, 32, and -24. The GCF of these values is 4.
As for the variables, the values are x^7, x^5, and x^4. The GCF is x^4
To factor this expression take out 4x^4 from each of the terms.
Coefficients should be divided by four and exponents should be subtracted by 4 since they have the same base (x).
The answer here is A.
