Step-by-step explanation:
first you have to see the triangle BCD
then hypotheses and perpendicular are given so you have to find base
after finding base. In rectangle ABCD DC is length and BC is breadth so now you can find area by using the formula A = l×b
Answer: Answer is C.
Step-by-step explanation: It is because positive numbers go to the right, and negative numbers to the left.
Hope that helps :)
Answer:
Therefore
15.
16.
17.
Step-by-step explanation:
15.
Using the Identity (a + b)(a - b) = (a² - b²) we get
Consider here a = 5c and b = 3 then we will have
.....as required
16.
Here Factorize 8 such that sum up to be 9
∴ 8 × 1 = 8 and 8 + 1 =9
... as required
17.
Here Factorize 21 such that sum up to be -10
∴ -3 × -7 = + 21 and -3 - 7 = - 10
........as required
Therefore

Answer:
264 ft³
Step-by-step explanation:
The following data were obtained from the question:
Pi (π) = 3.14
Height (h) = 21 ft
Radius (r) = 2 ft
Volume (V) =..?
The volume of the cylinder can be obtained as follow:
V = πr²h
V = 3.14 × 2² × 21
V = 3.14 × 4 × 21
V = 264 ft³
Therefore, the of the cylinder is 264 ft³
Answer:
x = 125.44
Step-by-step explanation:
you multiply both side by 7
so 7 • 17.92 = 7 • x/7
125.44 = x
