Answer:
172 cm².
Step-by-step explanation:
Total surface area = 56 + 16 +56 + 16 + 14 + 14
135 because vertical angles are congruent
Answer:
the slope is 2
Step-by-step explanation:
take y2 and y1 and subtract them, 11 - 5 = 6
then take x2 and x1 and subtract them, 5 - 2 = 3
then divide those 2 numbers, 6/3 and you get 2
Step-by-step explanation:
7*3y - 7*5 + 2*4y + 12
= 21y - 35 + 8y + 6
= 29y - 29
= 29(y-1)
Answer:
Step-by-step explanation:
Square Root of 225 is 15 (with -15 also it would work but let’s stick to positive root)
Now, the 1st Odd Number is 15 -2 = 13 and the 3rd Odd Number is 15 + 2 = 17.
The required Numbers are 13 and 17.
This works for 3 consecutive Even Numbers also.
Why does it work?
Because, if we have 3 numbers to be a-2, a and a+2 (Doesn’t really matter if a is positive or negative)
(a-2)*(a+2) = a^2 - 4
So, you see adding 4 to the Product of the 1st Number and the 3rd Number (a^2 - 4 + 4 = a^2) gives you the square of the Middle Number, which is a^2!
