Answer:

The answer to your question is SA = 1244.64 cm² ≈ 1245 cm²

Step-by-step explanation:

Formula

SA = 2B + PH

Process

1.- Calculate B

B = Perimeter x 6.93/ 2

B = (8 x 6) x 6.93 / 2

B = 166.32 cm²

2.- Calculate 2B

2B = 2(166.32)

     = 332.64 cm²

3.- Calculate PH

P = perimeter

P = 8 x 6

   = 48 cm

PH = 48 x 19

PH = 912 cm²

4.- Calculate SA

SA = 332.64 + 912

SA = 1244.64 cm²

Answer:

Question 8: 8.94

Question 9: 8.94

Step-by-step explanation:

Question 8: Using pythagorean theorem [a^2+b^2=c^2], we do (8*8)+(4*4) getting 80 which is our c^2. Now we find the square root of which is 8.94.

Question 9: Using pythagorean theorem [a^2+b^2=c^2], we do (5.3*5.3)+(7.2*7.2) getting 79.93 which is our c^2. Now we find the square root of which is 8.94.

Please correct or msg me if this is wrong.

Explain why y +1 = 1.2(x+2) and y-5= 1.2(x – 3) represent the same line, despite having
andrew11 [14]

Answer:

You can manipulate both equations into y = mx + b format and end up with the same result of y = 1.2x + 1.4

Step-by-step explanation:

y + 1 = 1.2(x + 2)

y = 1.2x + 2.4 - 1

y = 1.2x + 1.4

y - 5 = 1.2(x - 3)

y = 1.2x - 3.6 + 5

y = 1.2x + 1.4

So essentially, they're the same equation but in different forms.
