Answer:

see explanation

Step-by-step explanation:

(a + b)(a - b)

each term in the second factor is multiplied by each term in the first factor, that is

a(a - b) + b(a - b) ← distribute parenthesis

= a² - ab + ab - b² ← collect like terms

= a² - b²

Larry Thomas's charge account statement shows an unpaid balance of $800. The monthly finance charge is 1.5% of the unpaid balanc
lilavasa [31]

Answer:

The new account balance is <u>$812</u>.

Step-by-step explanation:

Given:

Larry Thomas's charge account statement shows an unpaid balance of $800.

The monthly finance charge is 1.5% of the unpaid balance.

Now, to find the new account balance.

Unpaid balance = $800.

Monthly finance charge of the unpaid balance = 1.5%.

Now, to get the new account balance:

$800 + 1.5% of $800.

=800+\frac{1.5}{100} \times 800.

=800+0.015\times 800.

=800+12.

=\$812.

Therefore, the new account balance is $812.

Use the drawing tool(s) to form the correct answer on the provided number line. Consider the given functions. Function 1 Functio
Anna007 [38]

Both functions decrease at (-1, 2)

<h3>How to determine the decreasing intervals of the function?</h3>

The complete question is added as an attachment

The polynomial function f(x) is represented by the graph.

From the graph, the polynomial function decreases at (-2, 2)

The absolute function is given as;

f(x) = =5|x + 1| + 10

The vertex of the above function is

Vertex = (-1, 10)

Because a is negative (a= -5), the vertex is a maximum.

This means that the function decreases at (-1, ∞)

So, we have

(-2, 2) and (-1, ∞)

Combine both intervals

(-1, 2)

This means that both functions decrease at (-1, 2)

See attachment 2 for the number line that represents the interval where both functions are decreasing

The figure shows a square, a regular pentagon and a regular hexagon put together. What is the measure of ∠BAC
Elan Coil [88]

Answer:

42

Step-by-step explanation:

One angle of a regular pentagon = 108°

One angle of a regular hexagon = 120°.

One angle of a square = 90°

∴ ∠BAC = 360 – (108 + 20 + 90) 360 – 318 = 42°

Answer:

15/16-3/4 is 3/16. (1/8 simplified)

Step-by-step explanation: Let the 4 turn into a 16. Multiply 4 by 4 to get 16. Then, multiply the numerator by the number you multiplied for the denominator. 3x4 is 12. Now, can subtract. 15-12=3.
