Subtract -6 on both sides
Now you have x/-2 on the left and 3 on the right
Then multiply -2 on both sides, leaving you with x on the left and -6 on the right
So x< -6

The simplified form of the equation is \rm -69.19x+38.2.

<h2>Given that</h2>

Equation; \rm -9.2(8x - 4) + 0.7(2 + 6.3x)

<h3>We have to determine</h3>

The simplified form of the equation;

<h3>According to the question</h3>

To determine the simplified form of the equation following all the steps given below.

Equation; \rm -9.2(8x - 4) + 0.7(2 + 6.3x)

<h3>To simplify the equation multiple the terms and solve.</h3>

Then,

The simplified form of the equation is,

\rm =-9.2(8x - 4) + 0.7(2 + 6.3x)\\&#10;\\&#10;= (-9.2) (8x)- (-9.2)(4) + (0.7)(2) + (0.7) (6.3x)\\&#10;\\&#10;=-73.6x -(-36.8) +(1.4)+(4.41x)\\&#10;\\&#10;= -73.6x+36.8+1.4+4.41x\\&#10;\\&#10;=-69.19x+38.2

Hence, The simplified form of the equation is \rm -69.19x+38.2.

6. a semicircle has as its diameter the hypotenuse of a right triangle shown below. determine the area of the semicircle to the
jeyben [28]

Answer:

A = 137.3cm^2

Step-by-step explanation:

Given

See attachment

Required

The area of the semicircle

First, we calculate the hypotenuse (h) of the triangle

Considering only the triangle, we have:

\cos(68) = \frac{7}{h} --- cosine formula

Make h the subject

h = \frac{7}{\cos(68)}

h = \frac{7}{0.3746}

h = 18.7

The area of the semicircle is then calculated as:

A = \frac{\pi h^2}{8}

This gives:

A = \frac{3.14 * 18.7^2}{8}

A = \frac{1098.03}{8}

A = 137.3cm^2
