54 and 21 and thats how i got it lol
Answer:
4+24u
Step-by-step explanation:
Step 1 Write it out
the expression written out is 4 times (1+6u)
Step 2 distribute
Now you distribute
4(1+6u)
4 times 1 is 1
then its 4 times 6u and you get 24u
so your answer is 4+24u and you cant add these two because the 4 doesn't has the same exact variable a the 24 has.
A. True, a rhombus is a parallelogram with equal sides. A rhombus has four congruent sides.
B. True, but there are two other ways to find the area of a rhombus: there is the "diagonals" method and the "trigonometry" method.
C. False, the area of a rhombus is not less than the area of a parallelogram because it will depend on the diagonals.
D. False, a parallelogram is not always a rhombus because the dimensions and other attributes of a parallelogram may vary while the rhombus will remain equal for all aspects.
E. True, if you use the base times height formula but if you used any of the other formulas this would be false.
Answer:
x^2+2hx+4=x
=>x^2 + 2hx +4 -x = 0
=> x^2 +hx + 4 =0
For one root, the roots have to be equal, so the discriminant = 0
b^2 - 4ac = 0
=> h^2 - 4(1)(4)=0
=> h^2 -16 = 0
=> h^2 = 16
Therefore h = 4 :)
Saying a function f is continuous when x=c is the same as saying that the function's two-side limit at x=c exists and is equal to f(c).
