Answer:
if breadth is y feet long
let length be y+4
Step-by-step explanation:
therefore,
area=(4+y)*y
area=4y+y2
Answer:
x = 2
Step-by-step explanation:
-12 = -2x - 4x
-12 = - 6x
x = -12/(-6) = 2
<span>A trend line shows the general pattern of the data, but does not try to connect all the data points is the correct choice about trend lines. It usually is the most general direction of the points.</span>
-3x+2 < 8
-2 -2
-3 /-3x <6/-3
x >-2
So x>-2
Answer:
b = 6 sqrt(2)
Step-by-step explanation:
Since this is right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
3^2 + b^2 = 9^2
9+b^2 = 81
b^2 = 81-9
b^2 = 72
Take the square root of each side
sqrt(b^2) = sqrt(72)
b = sqrt(36*2)
b = 6 sqrt(2)
