What is the value of the expression? Enter the answer in the box.<br> 4+(8 - 7) X6-1
e-lub [12.9K]
Answer: 9

Explanation: you would use PEMDAS to solve the algebraic expression first by doing parentheses so subtract 8 and 7 which leaves you with 4 + 1 times 6-1. You would then multiply 1 into 6 which would leave you with 4 + 6 - 1 which you would then sum up 4 and 6 which leaves you with 10-1 which would give you the answer of 9

So the answer would be 9

Hope this helps!

Help ASAP!! Geometry -
horrorfan [7]

Answer:

x = 9.27 cm

Volume = 289.2 cm³

Step-by-step explanation:

SA = Surface Area

SA = 229.2 cm²

P = Perimeter of Base

P = 3(6)

P = 18 cm

H = Height of Solid

H = x

A = Area of Base(Equilateral Triangle)

A = 6²√3 / 4

A = 36√3 / 4

A = 9√3

A = 9(1.732)

A = 31.176

A = 31.2 cm²

SA = Surface Area

SA = PH + 2A

229.2 = 18x + 2(31.2)

229.2 = 18x + 62.4

229.2 - 62.4 = 18x

166.8 = 18x

9.266 = x

9.27 = x

x = 9.27 cm

V = Volume

V = AH

V = 31.2(9.27)

V = 289.224

V = 289.2 cm³
