Answer:
about 0.53 and -0.17
Step-by-step explanation:
Since the 1 is on the other side of the equation, subtract it from both sides of the equation. Then you have a= 11, b=-4, and c=-1, so you substitute those values into the quadratic formula and the roots round to about that.
I hope that helped!

Answer:
16
Step-by-step explanation:
The figure shown is a trapezoid
Area of a trapezoid = 1/2(bottom base length + top base length) × height
Bottom base length = 7 units
Top base length = 1 unit
Height = 4 units
So area = 1/2 ( 7 + 1 ) × 4
==> add 7 and 1
Area = 1/2 (8) × 4
==> multiply 1/2 and 8
Area = 4 × 4
==> multiply 4 and 4
Area = 16
