The answer is C, 10.

When performing synthetic division, we bring down the first number in the box. We then multiply this number by the number outside the box, and place that result under the second number in the box. We add these two numbers and bring that sum down.

We then continue this process by multiplying this second number by the number outside the box, and place the result under the third number in the box. We then add the two numbers in the third column and bring the sum down. The missing number is under this column; that means it is found by adding 2+8, so it is 10.

Answer: Interest to be paid on the loan will be $6,468

Step-by-step explanation:

Isimple interest = Principal x Rate x Time

From the information given,

Principal = $11,550

Rate = 5.6% = 5.6/100 = 0.056

Time = 10years

Slot the values into the formula;

Interest= $11,550 x 0.056 x 10

The figure below shows a 39-inch ramp that is attacked to a deck.

Lelu [443]

Answer:

15 inches

Step-by-step explanation:

1. Use the Pythagorean Theorem: a^2+b^2=c^2

You are already given c (the longest side) and one of the legs which could be a or b.

2. Plug the numbers into the formula and square them.

a^2 + 36^2 = 39^2

Squaring the numbers gives you: a^2 + 1,296 = 1,521

3. Subtract 1,296 from both sides and take the square root of the result.

a^2 = 225

$\sqrt{225}$ = 15

3. -4x - 6

-3(x + 2) - x → ( distribute bracket by - 3)

= - 3x - 6 -x → (collect like terms)

=( - 3x - x) - 6 = - 4x - 6

4. A has the smallest value

A =( 2 - 3 ) = -1

B = 2 × 3 = 6

C = 2 + 3 = 5

D = $\frac{2}{3}$

A is negative while the others are all positive.

Thus A is the smallest value expression
