Answer:
B. -5
Step-by-step explanation:
this is quite simple, so what you are going to want to do is multiply -3 by 4, and -16, so distribute that and you'll end up with
-12x+48= -12
then you want to subtract 48 from both side to leave the x on one side alone
that will be -12x= -60
after that you have to divide both sides by -12 to find your x
so then you will see that your x is = -5! hope this helps!!
Answer:
3rd option
Step-by-step explanation:
Given
x³ - 7x² - 5x + 35 ( factor the first/second and third/fourt terms )
= x² (x - 7) - 5(x - 7) ← factor out (x - 7) from each term
= (x² - 5)(x - 7)
Answer:
14.1 =x
Step-by-step explanation:
Since this is right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin 42 = x /21
21 sin 42 = x
14.05174273 =x
Rounding to the nearest tenth
14.1 =x

Answer:
The answer to your question is Area = 9 3/8
Step-by-step explanation:
Data
length = 3 3/4 cm
width = 2 1/2 cm
Process
1.- Write the equation of the Area of a rectangle
Area = length x width
2.- Convert the values to improper fractions
3 3/4 = (12 + 3)/ 4 = 15/4
2 1/2 = (4 + 1) / 2 = 5/2
3.- Substitution
Area = (15/4)(5/2)
4.- Simplification
Area = 75/8
5.- Convert to a mixed fraction
9
8 75
3
6.- Result
Area = 9 3/8
