krek1111 [17]

2b^2 + 81/2 b + 4

basically 2b^2 + 16b + 49/2 b + 4
= (2b^2) + 16b+49/2b) + (4)
= 2b^2 + 81/2 b + 4

How do I do number 4

nikitadnepr [17]

Answer:

its 6.40

Step-by-step explanation:

you have to use the distance formula which is

$d=\sqrt(x2-x1)^{2} + (y2-y1)^2$

so points C is (-5,-1) and D is (0,3)

then you substitute the x

0--5=5^2

then

3--1+4^2=16

25+16=41

then square rout that and it equals 6.40

How would I solve 11/15 + 3/10 with work please?!

AnnyKZ [126]

First you need to find a common denominator. 11/15 = 22/30

3/10= 9/30

9/30+22/30= 1 1/30

Hope this helps!
