Answer:
A
Step-by-step explanation:
f(x)=x^2-4x+3
x coordinate: -b/2a
-(-4)/2(1)=4/2=2
and to find the y coordinate just plug in the value of -b/2a for x and solve for y
Answer: 29.2cm
Step-by-step explanation: perimeter of parallelogram; 2(a + b) where a = base, b = altitude
a = 8cm
b = 6.6cm
Perimeter = 2(8 + 6.6) = 2(14.6)
Perimeter = 29.2cm
Answer:
14
step by step explanation:
14
The area of a trapezoid is (a+b)/2 * h
a is the length of the small base which is the one on the top and is 4cm
b is the length of the big base which is the one at the bottom and is 4 + 3 + 3 = 10cm
h is the height which is 7cm
So the area is (4+10)/2 * 7
A= 14/2 * 7
A= 7 * 7
A= 49 cm^2
