Step-by-step explanation:
sorry I can only explain as there are no labels to each diagram
The first diagram is single and can solved using triangular formular given as 1/2 ×base × height
A = 1/2 × 5 × 12
A = 30cm^2..
as for the second one...it consist of 2 diagrams which will be solved separately before adding ...it can simply be done using Pythagoras theorem..
To get the smaller part ...out tita is 45degrees while our adjacent is 4 and opposite is x we are to find x which is the height...
using SOH CAH TOA...
WE HAVE TAN45= opp/adj
Tan45= x/ 4
Tan 45 =1 ...so
1 = x/ 4
and x= 4 ...
so...having our height as 4 and base as 4 ..
Area of smaller triangle become 1/2 × 4 × 4
A = 8cm^2 ...
......SOLVING FOR THE SECOND DIAGRAM ..
WE HAVE the height as ( dotted spot + undotted spot ) = 4 + 4 = 8cm
and our base can be gotten from
Tan45 = opp / adj
1 = 8/x ..
x = 8cm ....so the base is 8 and the height is 8
..
The Area becomes 1/2 × 8×8 = 32cm ...
Total area becomes 32cm + 8cm = 40cm^2
The answer is C)
Step-by-step explanation:
4x(x+1) - (3x-8)(x+4)
(4x^2+4x) - (3x^2+12x-8x-32)
(4x^2+4x - 3x^2-12x+8x+32)
4x^2-3x^2+4x+8x-12x+32
=x^2+32
Quadratic binomial
Answer:
The answer is the fourth option.
Step-by-step explanation:
First we need to find the measurement for 1 centimetre. To do this, we need to divide the given amount of miles (25) by the given number of centimetres (2).
25 / 2 = 12.5
1 cm = 12.5 miles
Now we need to find the distance of the next town.
If the next town is 5 cm, and 1 cm is 12.5 miles, we need to multiply 12.5 by 5.
12.5 * 5 = 62.5
<h3>So the next town is 62.5 miles away!</h3>
If you are asked to round this to the nearest whole number, it would be 63 miles.
