His average is 80%. You take the two scores add them up and divide by the number of scores.
Answer:
Step-by-step explanation:
let polynomial P(x)=ax³+bx²+cx+d
-3=-a+b-c+d
-2=d
-1=a+b+c+d
-1=a+b+c-2
a+b+c=1
-3=-a+b-c-2
a-b+c=1
a+b+c-(a-b+c)=1-1=0
2b=0
b=0
so a+c=1
6=8a+4b+2c+d
6=8a+4b+2c-2
8a+4b+2c=8
4a+2b+c=4
or 4a+0+c=4
4a+c=4
a+c=1
subtract
3a=3
a=1
1+c=1
c=0
reqd .P(x)=1x³-2=x³-2
The answer is A 100
because if you divide 1000by 100 your answer would be 100
because of the math
Sum of square of two sides must be equal to the square of third side.
Answer:
Area is 235
Step-by-step explanation:
Split the shape evenly so 11 x 14 and 9 x 9then multly and add
when slpitting up the number some times you have to add or subtract so to get 9 x 9 we just take 20 then take away 11 due to the line going through 20 and 20 - 11 = 9
9 x 9 = 81
11 x 14 = 154
81 + 154 = 235
or
Simular to the first one but the cutting line is different. this time the line cuts through 14
9 x 20 = 180
11 x 5 = 55
180 + 55 = 235
