Find the product.
(x-3)(x+5)
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
the sides lenghths of a triangle are 9, 12, and 18 is this a right triangle?
Answer:
By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.
What are the x- and y-intercepts?
0,3
1,20
3,36
5,28
7,0
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).

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
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.

Answer:
1: 0.80
2: 1.30
Step-by-step explanation:
Hope this helps
Answer:
0.80 and 1.30
Step-by-step explanation:
0.80, 1.05, 1.30, 1.55, 1.80, 2.05
... + 0.25 = 1.05
= 1.05 - 0.25
= 0.80
0.80 + 0.25 = 1.05
1.05 + 0.25 = 1.30
1.30 + 0.25 = 1.55
1.55 + 0.25 = 1.80
1.80 + 0.25 = 2.05

I'm really struggling with this problem can someone please give me an examples like this problem or explain how to solve it an problems like it.
Answer:
Step-by-step explanation:
Ok so I'm not 100% sure how to solve this but what I would do is use the equation a^2 + b^2 = c^2 this equation is used to solve for the hypotenuse or the longest side of a triangle. To find a^2 you would do (21+15)^2 (Also this symbol ^ is the power symbol) and the answer would be 1296. b^2 would be 25^2 or 625. The equation turns out to be 1296 + 625 = c^2. c^2 (or x in this case) would be 1921. To find just c and not c^2 you would find the square root of 1921 which is 43.8292140016 or if rounded would be 43.8. Also this might not help if I misinterpreted the question...

Calculate the length AB
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

Answer:
what do you need help with?
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Slope formula is Δy/Δx or (change in y)/ (change in x).
Apply that formula:
You know that 1-(-1) = 2, therefore for a slope of 1/5, the only possibile denominator is 10: 2/10 simplifies to 1/5.
So. What subtracted by 6 is equal to 10? 16.
