Find the product.
(x-3)(x+5)

Answers

Answer:

x2+5x-3x-15=x2+2x-15

Step-by-step explanation:

(x)(x)=x2,(x)(5)=5x

(-3)(x)=-3x,(-3)(5)=-15

Answer: X^2 + 8x -15

Step-by-step explanation:

Use the foil method.

First, outer, inner, last

Multiply the first numbers inside each parenthesis. X*X = x^2

Next multiply the outer number in each parenthesis. X*5 = 5x

Then multiply the inner numbers of the parenthesis. -3*x= 3x

Finally multiply the last numbers in the parenthesis. -3*5 = -15

Now add all of these together

X^2 + 5x + 3x + -15

Combine like terms

X^2 + 8x -15

X can be solved from here, however it does not seem that you are asked to solve for x

Question 1 (25 points)
An isosceles triangle has a base 8.8 units long. If the congruent side lengths have measures to the first decimal place, what is
the shortest possible length of the sides?
4.5
8.9
4.3
Od
17.7
b
С

Answers

Answer:

4.5

Step-by-step explanation:

For any triangle, the basic principle for these types of problems is that the sum of the 2 shorter sides has to be greater than the longest side, otherwise it is not a triangle, even if it's equal to the longest side.

So, let's look at the first option. 4.5. Since this is an isosceles triangle and the base is 8.8 units, the other side has to be 4.5 as well. 4.5+4.5=9. 9 > 8.8. So, we can immediately eliminate options 8.9 and 17.7. What about 4.3? Well, 4.3+4.3= 8.6, but 8.6 < 8.8, so 8.6 is wrong. So, the answer is 4.5.

What are the x- and y-intercepts?

0,3

3,36
5,28
7,0

Answers

The required x-intercept is (7, 0) and the y-intercept is (0, 3).

What is the intercept in the equation?

In the equation intercept is the value of the linear function where either of the variables is zero.

Here,
To find the x-intercept, we need to find the point at which the graph intersects the x-axis. This occurs when the y-coordinate is zero.

The x-intercept is therefore (7, 0).

To find the y-intercept, we need to find the point at which the graph intersects the y-axis. This occurs when the x-coordinate is zero.

The x-intercept is therefore (0, 3).

Thus, the x-intercept is (7, 0) and the y-intercept is (0, 3).

Calculate the length AB

Answers

Answer:

14.004m

Step-by-step explanation:

Using the SOH CAH TOA trigonometry identity

Tan theta = opposite/adjacent

Given

AB = opposite

BC = adjacent = 20cm

theta = 35 degrees

Substitute

tan 35 = AB/20

AB = 20tan35

AB = 20(0.7002)

AB = 14.004cm

Hence the length of AB is 14.004m
