5 0

Answer:

Step-by-step explanation:

Substitute the x- coordinate into the equation and if the result is equal to the y- coordinate then it satisfies the equation, that is

y = 7(- 1) = - 7 ≠ 5

Then (- 1, 5 ) is not a solution to the equation

Find the value of x for the given equation : 2 (x-1) - 6 =24

olasank [31]

Answer:

x = 16

Step-by-step explanation:

2(x - 1) - 6 = 24 ( add 6 to both sides )

2(x - 1) = 30 ( divide both sides by 2 )

x - 1 = 15 ( add 1 to both sides )

x = 16

Find the surface area of the attached figure and round your answer to the nearest tenth, if necessary.

mariarad [96]

Answer:

$S.A = 246.6 in^2$

Step-by-step explanation:

The figure given above is a square pyramid, having a square base and 4 triangular faces on the sides that are of the same dimensions.

Surface area of the square pyramid is given as: $B.A + \frac{1}{2}*P*L$

Where,

B.A = Base Area of the pyramid = 9*9 = 81 in²

P = perimeter of the base = 4(9) = 36 in

L = slant height of pyramid = 9.2 in

Plug in the values into the given formula to find the surface area

$S.A = 81 + \frac{1}{2}*36*9.2$

$= 81 + 18*9.2$

$= 81 + 165.6$

$S.A = 246.6 in^2$
