A. (Number of sides - 2) x 100, so
6-2= 4 x 180
= 720° is the sum of all angles in a hexagon
84 + 87 + 128 + 150 + 103 = 552
720 - 552 = 168
X = 168°

2. Angles in a triangle sum up to 180°
36 + 57= 93
180 - 93 = 87
A= 87°

Answer:

$B.\:\: g(x)=4(2^x)$

Step-by-step explanation:

The given function is $f(x)=2^x$ .

If an exponential function is of the form; $F(x)=a(b^x)$ , then $0$ will vertically shrink the base function $f(x)=b^x$

and $a\:>\:1$ will vertically stretch the graph by $a$ units.

The correct answer is B.

8. Select all the numbers that irrational

Answer:

Answers are square root of 2, square root of 7,

Step-by-step explanation:

Irational is a number that is never ending.

Square root of 2 is irrational since there is no pattern to the number after the decimal.

10/ sqrt of 100. Sqrt of 100 is 10. 10/10 = 1 so this is not a irrational.

Sqrt of 7 does not have a pattern after the decimal point so it is irrational.

5.87 with a dash on top is rational since it means it has a pattern of continues 87's.

Last one it is equal to 2 so it is rattional.

Step-by-step explanation:

$\frac{5 {}^{ - 4x + 7} }{125 {}^{x} }$

$\frac{5 {}^{ - 4x + 7} }{5 {}^{3x} }$

$5 {}^{ - 4x + 7 - 3x}$

$5 {}^{ - 7x + 7}$

A rectangular prism measures 3ft by 6ft by 5ft. If the dimensions of the box were all quadrupled. How would the surface area of

Blababa [14]

The surface area of a shape is the amount of space on the shape

When the dimensions are quadrupled, the new surface area would be 16 times the initial surface area

<h3>How to determine the surface area</h3>

The surface area of a rectangular prism is:

$S = 2 * (lw + lh + wh)$

When quadrupled, we have:

$S_2 = 2 * (16lw + 16lh + 16wh)$

Factor out 16

$S_2 =16 * 2 * (lw + lh + wh)$

Substitute $S = 2 * (lw + lh + wh)$

$S_2 =16 * 2 * S$

The above means that:

The new surface area would be 16 times the initial surface area
