Since AB is 6cm, and you are working with a right triangle, AC is also 6cm, so your answer is A: 6cm

Answer:

1183

Step-by-step explanation:

Common difference:

d = 31 - 15 = 16

nth term:

$a_n = a_1 + (n - 1)d$

Here, $a_1 = -1$

$a_{75} = -1 + (75 - 1)(16)$

$a_{75} = 1183$

Which is an equation of a line through (7,1) and perpendicular to y=-x+3

zysi [14]

Answer:

The answer is y=-1x+8 or you can write it this way y=-x+8 either way will work fine.

Step-by-step explanation:

y=mx+b

m=-1

y-y=m(x-x¹)

y-1=-1(x-7)

y-1=-1x+7

+1 +1

Which are steps the could be used to slove 0=9(x2+6x)-18 by completing the square

Elis [28]

Answer:

(x+3)²-11=0

Step-by-step explanation:

0=9(x2+6x)-18

0= 9x² +54x-18

0= 9( x²+6x-2) taking 9 common

0= x² +6x-2 (breaking the mid term to find the second element of the square

0 = (x)² +2(x)(3) +(3)² -2 -9 adding and subtracting the second element

0= (x+3)² -11 summing up
