4 × (3 - 1 × 3) + 8 ÷ 2^3
Remember PEMDAS: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. Parentheses first: (3 - 1 × 3) (3 - 3) (0)
Now exponents: 2^3 8
Now the rest of the equation: 4 × 0 + 8 ÷ 8
Multiplication and Division: 0 + 1
Addition and Subtraction: 1
Answer is 1.

Using PEMDAS, simplify what's in the parentheses.

(3-1 x 3) = (3-3) = 0


Then, simplify the 2 cubed.

2^3 = 8


Now, simply just multiply and dicide the expression first and then add.

4 x (0) + 8 / 8

0 + 1

1

Your final answer should be 25.

Answer: 15.7 (1 decimal place)

Step-by-step explanation:

The formula for the circumference of a circle is d(diameter) x π(pi).

The diameter of this is 5 so you would do 5xπ=15.7 (1 decimal place)

Solve 3^x − 2 = 3^7<br><br> A. 2<br> B. 5<br> C. 7<br> D. 9
Vikki [24]

Answer:

C) 7

Step-by-step explanation:

3^x−2=2187

Step 1: Add 2 to both sides.

3^x−2+2=2187+2

3^x=2189

Step 2: Solve Exponent.

3^x=2189

log(3x)=log(2189)        <<Take log of both sides

x*(log(3))=log(2189)

x= log(2189)/log(3)

x=7.000832

The measure of two opposite interior angles of a triangle are and. The exterior angle of the0x−14x+4triangle measures. Solve for
11111nata11111 [884]

Answer:

60 degrees

Step-by-step explanation:

Restructured question:

The measure of two opposite interior angles of a triangle are x−14 and x+4. The exterior angle of the triangle measures 3x-45 . Solve for the measure of the exterior angle.

First you must know that the sum of interior angle of a triangle is equal to the exterior angle

Interior angles = x−14 and x+4

Sum of interior angles = x-14 + x + 4

Sum of interior angles = 2x - 10

Exterior angle = 3x - 45

Equating both:

2x - 10 = 3x - 45

Collect like terms;

2x - 3x = -45 + 10

-x = -35

x = 35

Get the exterior angle:

Exterior angle =   3x - 45

Exterior angle = 3(35) - 45

Exterior angle = 105 - 45

Exterior angle = 60

Hence the measure of the exterior angle is 60 degrees

<em>Note that the functions of the interior and exterior angles are assumed. Same calculation can be employed for any function given</em>
