Answer:
a, c) see below
b) trapezoid
d) 80 square units
Step-by-step explanation:
a, b, c) See the attached plot. The different-length horizontal bases make this a trapezoid.
__
d) The area of the original is ...
A = (1/2)(b1 +b2)h = (1/2)(1+4)(2) = 5
Dilation by a factor of 4 multiplies the area by a factor of 4² = 16.
The area of the larger trapezoid is ...
5 × 16 = 80 . . . . square units
__
Of course, you can use the area formula, too:
A = (1/2)(b1 +b2)h = (1/2)(4 +16)(8) = 80 . . . . square units

Step-by-step explanation:
Answer: 15
Step-by-step explanation:
Plug in 8 for e and solve
8 - ((sqrt 8 + 1) + 2)) + (8 - 3sqrt8) sqrt8 - 4
Answer: 450 minutes
Step-by-step explanation:
4 hours and 30 minutes equals 4.5 hours.
3+4.5=
7.5 hours
1 hour equals 60 minutes
Hence,
7.5*60=
450 minutes
Answer:
5.25
Step-by-step explanation:
If CD is perpendicular to AB, a right angle is formed by the perpendicular lines at the base of the triangle. If we know that AB is 3 we can divided that by two to use half the triangle and create a right trianle with a base of 1.5 (half of 3) a height of rad 3 now all we have to do is use P-Thags to find AC which is the hypotenuse. After doing 1.5 squared + rad 3 squared = ac squared you will get the answer of AC = 5.25
