Answer:
x=58, m<DCB=56°
Step-by-step explanation:
Ok the sum of those two angles should equal 180 degrees so,
2x+8+x-2=180
solve the equation
3x+6=180
3x=174
x= 58
M<DCB=x-2--> 58-2=56
Answer:
f(x)=|x−13|+11
To find the x
coordinate of the vertex, set the inside of the absolute value x−13 equal to 0. In this case, x−13=0
.
x−13=0
Add 13
to both sides of the equation.
x=13
Replace the variable x
with 13
in the expression.
y=|(13)−13|+11
Simplify |(13)−13|+11
.The absolute value vertex is (13,11)
hope this helps ;)
Answer:
4(2e - 3)(3e + 1)
Step-by-step explanation:
Given
24e² - 28e - 12 ← factor out 4 from each term
= 4(6e² - 7e - 3) ← factor the quadratic
Consider the factors of the product of the e² term and the constant term which sum to give the coefficient of the e- term.
product = 6 × - 3 = - 18 and sum = - 7
The factors are - 9 and + 2
Use these factors to split the e- term
6e² - 9e + 2e - 3 ( factor the first/second and third/fourth terms )
= 3e(2e - 3) + 1 (2e - 3) ← factor out (2e - 3) from each term
= (2e - 3)(3e + 1)
Then
24e² - 28e - 12 = 4(2e - 3)(3e + 1) ← in factored form
Answer:
21
Step-by-step explanation:
-(-26) would be positive 26 because one negative multiplied by another negative equals a positive. We are left with -5+26 which would equal 21.
Answer:
About 48 hours or 2 days.
Step-by-step explanation:
360 + 360 = 720 + 360 = 1080 + 360 = 1440
12x4=48
