We are given with three lengths of a triangle expressed in terms and variables: (3x – 4) feet, (x^2 – 1) feet, and (2x^2 – 15) feet. The perimeter of the triangle is equal to the sum of the three sides of the triangle. In this case, the sum is 3x^2 + 3x -20. When x is equal to 4, we substitute <span>3*16 + 3*4 -20 equal to 40 feet.</span>
Answer:
The two numbers are -419 and -2095.
Step-by-step explanation:
5x=y
x-y=1676
----------------
x-5x=1676
-4x=1676
x=1676/-4
x=-419
5(-419)=y
y=-2095

Answer:
38.28cm^2
Step-by-step explanation:
Area of rectangle = 24cm^2
Area of rectangle = 8cm^2
Area of semicircle = 6.28cm^2
Step-by-step explanation:
the two opposites Angles of this quadrilateral are equal, again the angles should sum up to 360
t-9+t-91+t-16+t+25=360
4t=360-101
4t=259
t=64.75
