asinus made a small math mistake b^2 = 36 not 9 ( b is 6 not 3)
using the Quadratic Formula as asinus showed the answer x = 3/2 +- sqrt(7) / 2
x(x-3i)(x+3i)(x-4+i)(x-4-i)
which , when multiplied through =
x^5 - 8 x^4 + 26 x^3 - 72 x^2 + 153 x
Angle 1 and angle 7 are supplementary
13x+9 + 5x+9 = 180 find the value of x
then you can calc the value of angle 7 which is the same value as angle 6
Assuming the two horizontal lines are parallel
180 - 67 - 85 = ?
Sam has a 1/4 hr head start at 3.5 m/hr
3.5 m/h x 1/4 hr = .875 miles
Al closes this distance in 20 minutes = 1/3 hr
he is thus moving .875 m/1/3 hr FASTER than Sam = 2.625 m/hr faster
3.5 + 2.625 = 6.125 m/hr
There are 4 creases in the 3x3 totaling 18 inches each crease is 4.5 in
10 x 10 will have 18 creases that are 10/3 longer
18 * 10/3 * 4.5 = 270 inches
Tiger King annual salary = 55 000 + 2500n n = number of years
Carol Baskin annual salary = 62 000 + 2000n now equate them
55 000 + 2500 n = 62 000 + 2000 n and solve for n
The two 'x' angles are supplementay
6x+7 + 3x-16 = 180 solve for 'x' then use this answer as follows
the two lower angles are equal
11y - 32 = 6x+7 solve for 'y'
it is not a perfect cube
I do not under stand the second part of your question.... divideng by .912847483 will make it a perfect cube of 22
dividinb by .07776 will make it a perfect cube of 50
etc etc etc
Perimeter of rectangle is 20 so width is 4 making CD = 5
Trapezium area = 6 x 1/2 (3+5) = 24 cm2
