Answer:
24x^2
Step-by-step explanation:
When expanded (x+2)^4= x^4+8x^3+24x^2+32x+16
The only term that matches with these is 24x^2
Answer:
x = 5
Step-by-step explanation:
According to the Pythagorean theorem a²+b²=c²
In this case its:
x² + 12² = 13²
169 - 144 = x²
x² = 25
x = 5
If 4/5 of the total is 48, the total can be found by dividing it by 4 and multiplying it by 5:
48/4 = 12
12*5 = 60.
Answer:
(13,12)
Step-by-step explanation:
The value of x can be found by adding the two angles and setting them equal to 180 because they are on a straight line.
3h + 18 + 15h = 180
18h + 18 = 180
18h = 162
h = 9
So the value of h is 9
