The sum of cubes formula:
(4x28)+64
112+64
176
Rounded to the nearest ten it would be 180
Answer:
x=-9
Step-by-step explanation:
1. 7-3x=34
2. Subtract 7 from both sides to get -3x=27
3. Divide by -3 from both sides to get x by itself which turns out to be x=-9, for 27÷(-3)=-9
Legs legnth a and b, and hypotnuse c
a^2+b^2=c^2
legs are 9 and 12
a=12
b=9
12^2+9^2=c^2
144+81=c^2
225=c^2
sqrt both sides
15=c
the legnth of the hyptonuse is 15 inches
