It’s 4.2 because it’s and given and you add then yeah you get the point
My guess is that there is 5 angles and 5 sides... because i divided 10 in half
likeee this
10 ÷ 2 = 5
and bam we have our answer
Answer:
0 ways...
Step-by-step explanation:
First find one pair.
x and x + 1
2x + 1 = 100
2x = 99
x = 49.5
49.5 and 50.5
Since the only way is with decimals, there are 0 ways.
Answer:
2.44
Step-by-step explanation:
Given: x³ + 2x² - 5ax - 7 and x³ + ax² - 12x + 6
Also, R1 + R2 = 6
in order to find the value of a:
Let p(x) = x³ + 2x² - 5ax - 7 and q(x) = x³ + ax² - 12x + 6
Using remainder theorem i.e if a polynomial p(x) is divisible by polynomial of form x - a then remainder is given by p(a).
Then,
R1 = p( -1 ) = (-1)³ + 2(-1)² - 5a(-1) - 7 = -1 + 2 + 5a - 7 = 5a - 6
R2 = q( 2 ) = 2³ + a(2)² - 12(2) + 6 = 8 + 4a - 24 + 6 = 4a - 10
Now,
R1 + R2 = 6
5a - 6 + 4a - 10 = 6
9a = 22
a=2.44
Therefore, Value of a is 2.44
