A right triangle has legs of lengths 5 and 7. Find the exact length of the hypotenuse. If the answer is not a whole number, leave it in square root form.
Answer:
√74
Step-by-step explanation:
We know the pythagorian triplet that,
A^2 + B^2 = Hypotenuse^2
Or, 5^2 + 7^2 =Hypotenuse ^2
Or, 25+49= Hypotenuse^2
Or, 74 = Hypotenuse^2

What is linear expression?A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
We have to given that;
Sam bought a soft drink for four dollars and six candy bars.
And, He spent a total of 22 dollars.
Let the cost of each candy = x
So, We can formulate by the given condition,

Answer:
How do you multiply 18 by 5/6? Here we will show you step-by-step how to solve 18 times 5/6, which can be written as follows:
18
x
5
6
Step 1: Setup
First of all, note that 18 is the same as 18/1 since 18 divided by 1 is 18. Therefore, start by setting up the problem like this:
18
1
x
5
6
Step 2: Multiply
Multiply the numerators together (18 x 5 = 90) and multiply the denominators together (1 x 6 = 6) and make it into one fraction like so:
90
6
Step 3: Minimize
The greatest common factor of 90 and 6 is 6. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:
15
1
Step 4: Convert
Convert the improper fraction above to a whole number to get the answer:
15
That's it! Now you know how to calculate 18 times 5/6.
Answer:
15
Step-by-step explanation:
First turn the 18 into a fraction: 18/1
Next put the two fractions into an equation: 5/6 x 18/1 = ?
Then we mutiply the top numbers and the bottom numbers: 90/6
Finally since the fraction is top heavy, we divide to make it eithera lower fraction or a full number: 90/6 = 15
Your final answer will be 15 :)

Answer:
w=-8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
39−12w=7−16w
39+−12w=7+−16w
−12w+39=−16w+7
Step 2: Add 16w to both sides.
−12w+39+16w=−16w+7+16w
4w+39=7
Step 3: Subtract 39 from both sides.
4w+39−39=7−39
4w=−32
Step 4: Divide both sides by 4.

Answer: E. (x+5)^2 + (y-5)^2 = 9
Step-by-step explanation:
The equation of a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.
We are given that the center is (-5,5), which means that h = -5 and k = 5.
We are also given that the radius (r) = 3, which means r^2 = 9.
Therefore, the equation should be (x-(-5))^2 + (y-5)^2 = 9.
--> (x+5)^2 + (y-5)^2 = 9

Hello people ~
factorise: x^2 + 15x + 26
Answer:
(x +13)(x + 2)
Step-by-step explanation:
Sum = 15
Product = 26
Factors = 2 , 13
When we add the factors , we get 15 ( 13 +2 = 15)
When we multiply 2 and 13, we get 26 (13*2 = 26)
x² + 15x + 26 = x² + 13x +2x + 26
=x(x + 13) + 2(x + 13)
= (x +13)(x + 2)
So far as to attempt this question we can do either it by factorisation method by creating factors OR by splitting middle term method.
[tex]\mapsto\sf{ {x}^{2} + 15x + 26}[/tex]
Splitting middle term 15x in terms of 13x and 2x gives their sum to 15x and their product is equal to 26.
[tex]\mapsto\sf{ {x}^{2} + 13x + 2x + 26 = 0}[/tex]
[tex]\mapsto\sf{x(x + 13) + 2(x + 13)} = 0[/tex]
[tex]\mapsto\sf{(x + 2)(x + 13) = 0}[/tex]
CASE 1:
[tex]\mapsto\sf{x + 2 = 0}[/tex]
CASE 2:
[tex]\mapsto\sf{x + 13 = 0}[/tex]
Thus,
[tex]\sf{ \therefore \: ( {x}^{2} + 15x + 26) = (x + 2)(x + 13)}[/tex]
