Answer:
Step-by-step explanation:
The area of a trapezoid is the average of the parallel bases times the height or distance between the two bases
A=h(b1+b2)/2
Here we have h=8cm, b1=6cm, and b2=11cm so
A=8(6+11)/2
A=8(17)/2
A=4(17)
A=68 cm^2
The answer when you simply is B. 4^2
We'll represent the distance as d and the time as t.
d= 3(t+7) because Gilda is 7 minutes late when travelling 3 mph
d= 4(t-5) because Gilda is 5 minutes early at 4 mph
d= 3t + 21
d= 4t -20
3t +21 =4t -20
41=t
d= 3(41) +21= 144
The distance is 144 miles.
Answer:
x-int: (-1, 0), (-11, 0)
y-int: (0, 11)
Step-by-step explanation:
To find x-int, set equation equal to 0:
x² + 12x + 11
(x + 1)(x + 11)
x = -11, -1
To find y-int, set <em>x</em> = 0
f(0) = 0² + 12(0) = 11
f(0) = 11
