The answer would be -18 and 3
the answer is
<span>[√8k ]² =k²,
so 8k=k² which implies k² - 8k= 0, and (k
– 8)k= 0, so k = 8 or k =0</span>
Using the modified Pythagorean equation sqrt((6-4)^2 + (2-(-2))^2 = c^2, you get the sqrt(4 + 16) or sqrt 20. Factor the 20 into sqrt(4x5) you get 2xsqrt(5)
x≤-7
First , use the distributive property :
3(x-4)≥5x+2
3x-12≥5x+2
Subtract 5x on both sides :
3x-5x-12≥2
Now , add 12 on both sides :
3x-5x≥2+12
3x-5x≥14
Subtract the x's :
-2x≥14
Divide by -2 on both sides and watch what happens :
x≤-7 (notice that the inequality sign changed from "greater than or equal to" to "less than or equal to")
If we divide both sides of an inequality by a negative number , we change the inequality sign .
Answer:
B is correct option
Step-by-step explanation:
The correct option is B:
Convert 3 1/2 inches in feet by proportion:
3 1/2 = 7/2
1/4 / 7/2 = 1/x
1/2 / 7 =1/x
1/2 *x = 7
x= 7*2
x= 14ft
Convert 5 1/2 into feet
5 1/4 = 21/4
1/4 / 21/4 = 1/y
THE DENOMINATORS WILL BE CANCELLED OUT BY EACH OTHER.
1/21 = 1/y
y = 21ft
Therefore it is 14ft by 21ft, which is option B....
