Answer: -4/7

Step-by-step explanation:

To find the slope, let's change the equation to slope-intercept form.

4x+7y=9              [subtract both sides by 4x]

7y=-4x+9           [divide both sides by 7]

y=-\frac{4}{7}x+\frac{9}{7}

Now, we know the slope is -4/7.

Answer:

D

Step-by-step explanation:

Lateral SA = area of the 4 triangles

Formula to be used :-

Area (triangle) = 1/2bh

=> 4 x 1/2 x 9 x 12

=> 108 x 2

=> 216 cm²

Total SA = LSA + area of the square

Formula to be used :-

Area (square) = side length x side length

=> 216 + 9 x 9

=> 216 + 81

=> 297 cm²

<u>The correct option is (D).</u>

Neko [114]
Area of a triangle can be calculated as:

Area = 0.5 x Base x Height

Area is given to be 52 in²
Height is 13 inches.
We are to find the base b of the triangular shaped guitar.

Using the values in above formula, we get:

52=0.5(13)(b) \\  \\ &#10;b= \frac{52}{0.5(13)} \\  \\ &#10;b=8

Thus the base of triangular shaped guitar will be 8 inches.
