Answer: the smaller number is 11, and the larger number is 28
Step-by-step explanation:
Let x = the smaller number; then the greater number is 3x-5. When you add these they must equal 39, so:
x + (3x-5) = 39
4x - 5 = 39; now add 5 to both sides:
4x = 44; now divide both sides by 4, and you get x =11, which is the smaller number. The larger number would be 3(11)-5 = 33 - 5 = 28
I think your posting problem your missing an x after 28.
Therefore your answer is
C. (2x+7)(2x+7)
To check use distributive
2x(2x)+2x(7)+7(2x)+7(7)
4x^2+14x+14x+49
4x^2+28x+49
7/9 because if you simplify 21/27 you have to divide it by something that can go into both equally, which in this case is 3
Answer:
r = C / (2pie)
Step-by-step explanation:
C = 2pie x r
divide both sides by 2pie to isolate r
C / (2pie) = r
r = C / (2pie)
Answer:
y=4x-2
Step-by-step explanation:
if slope is 4, gradient is 4 so y=4x +c
given y intercept of -2,, y=4x -2
c=-2
