2/X^2=4/X+1 times by both denominators
2(x+1)=4(x^2)
2x+2=4x^2
4x^2-2x-2=0
(2x+1)(2x-2)=0
x=2x+1 or 2x-2
x=-1/2 or 1
Answer:
83 is the measure of x.
Step-by-step explanation:
A triangle is equal to 180 degrees. So 180 - 53 - 44 = 83.
Answer:
-(x - 7)(x + 6)
Step-by-step explanation:
Step 1: Factor GCF
-1(x² - x - 42)
Step 2: Factor quadratic
-1(x - 7)(x + 6)
Use distributive property: (24/4x-8/4)-(72-6x)
Simplify: 6x-2-72+6x
Simplify: 12x-74
12x-74
Answer:
a) 21+30+10+4+19+31+7+17+4=148
148 divided by 10= 14.8
b) 148+17=165
165 divided by 11= 15
Step-by-step explanation:
In math, the mean is the average of a set of numbers. To find the mean of a data set, add up all of the numbers in the set, and then divide that total by the amount of numbers in the set.
