If a, b and c are the lengths of a right triangle and c is the longest side, then:

$a^2+b^2=c^2$

We have a = 18cm, b = 24cm and c = 30cm. Substitute and check:

$L_s=18^2+24^2=324+576=900\\\\R_s=30^2=900\\\\L_s=R_s$

<h3>Answer: It's the right triangle.</h3>

Graph the system of linear inequalities, please explain the process in solving this problem so I know how to do ones similar to

Ierofanga [76]

Graph the system of linear inequalities

x + y > 5

- x - y < -5

First we graph x + y >5

Step 1: replace > symbol by = sign

x + y =5

step 2 : Solve the equation for y

x + y =5 (subtract x from both sides)

y = 5 - x

step 3: Now we make a table . plug in some number for x and find out y

x -----> y

-1 -----> 6 ( y=5-x => y=5-(-1)= 6)

0 -----> 5 ( y=5-x => y=5-(0)= 5)

1 -----> 4 ( y=5-x => y=5-(1)= 4)

Step 4: we graph the table.

step 5: Shade the region that satisfies our inequality

x + y > 5. Greater than symbol implies that we shade the graph to the right

Graphing second inequality - x - y < -5

All terms have negative sign . so divide all the terms by -1. When we divide an inequality by -1 its sign changes

- x - y < -5 becomes x + y > 5

Follow the same steps to graph this inequality

After dividing the second equation by -1 , we got the same as the first equation.

So we will get the same graph

Both graphs overlaps

The graph of first and second inequality overlaps

Probability that people like pizza is p(a) = 0.70. probability that people like burger is p(b) = 0.40. probability that people l

suter [353]

By addition theorem of probability,

P(AUB) = P(A) + P(B) -P(A∩B)
or
P(A or B) = P(A) +P(B) - P(A and B)
P(A or B) = 0.7 + 0.4 - 0.3 = 0.8

Therefore, the probability that randomly selected person likes pizza or burger is 0.8

The graph of the parent function f(x) = x3 is translated to form the graph of g(x) = (x – 1)3 + 2. Which is the graph of g(x), t

Ivahew [28]

Please, Moody, use " ^ " to denote exponentiation:

f(x) = x^3 and g(x) = <span>(x – 1)^3 + 2

Once you have drawn the graph of f(x) = x^3, you get the graph of g(x) by translating the entire graph of f(x) one unit to the right and then translating the result graph 2 units UP.</span>

How do I factor this

melamori03 [73]

There is a factor of 10p in each term that is common, and thus, you can take them out of each term to yield 10p(p² - 196).
Now, 196 is a perfect square. That is, there is a real number that when multiplied by itself gives 196 (14).
Since p² - 14² is a difference of two squares, we can rewrite it as (p + 14)(p - 14).

So, our factored form is 10p(p + 14)(p - 14)
