Is that the whole problem because I'll find it but I need all the information
Answer:
12
Step-by-step explanation:
Average age of 5 boys = 11 year
Sum of age of 5 boys = 11*5 = 55
Age of sixth boy = 17 years
Sum of age of 6 boys = 55 + 17 = 72
Average age of 6 boys= 72/6 = 12
Distribute 1/4 to all terms within the parenthesis
9 - 5 = 4
1/4(16x + 60) = (16x + 60)/4 = 4x + 15
4 = 4x + 15
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Subtract 15 from both sides
4 = 4x + 15
4 (-15) = 4x + 15 (-15)
4 - 15 = 4x
-11 = 4x
Isolate the x. Divide 4 from both sides
(-11)/4 = (4x)/4
x = -11/4
hope this helps
The sum of angles in triangle is equal to 180 degrees, so we need to check the sum of 60, 60 and 70
60+60+70=190
190>180, so it's false
Answer: False
We have
2x³+3x²+2x-4-(x³-2x²-x-1). Using the distributive property, we get
2x³+3x²+2x-4-x³+2x²+x+1
Adding and subtracting like terms (e.g. x³+3x³=4x³), we get
x³+5x²+3x+3
