Answer:
15 squre units
Step-by-step explanation:
The area of the rectangle is the product of its length and width. The length is AB = 5 units; the width is BC = 3 units. Then the area is ...
A = LW
A = (5 units)(3 units) = 15 units²
The area of rectangle ABCD is 15 square units.
Answer:
x = -3, 4/5
Step-by-step explanation:
To factor the equation, you need to find factors of (5)(-12) that have a sum of (+9).
(5)(-12) = -60 = 60(-1) = 30(-2) = 15(-4) = 12(-5) = 10(-6)
The factors 15 and -4 have a sum of 9, so we can factor the equation as ...
5x² +15x -4x -12 = 0
5x(x +3) -4(x +3) = 0 . . . . factor pairs of terms
(5x -4)(x +3) = 0
The solutions are the values of x that make these factors zero:
5x -4 = 0 ⇒ x = 4/5
x +3 = 0 ⇒ x = -3
The solutions are x = -3 or 4/5.
You have to separate the coefficient, "-4.3" from the variable "g', by using the inverse operation then doing it to the other side. You would divide 25.8 by -4.3 to get -6 <--Answer
Hello!!
Total = 3/7 + 4/5 + 2/3
= 0.428571429 + 0.8 + 0.66666667
= 199/105
= 1.89524.....
≈ 1.90 (rounded to two decimal places)
Good luck :)
