Answer:
10 x + 2 x^2
Step-by-step explanation:
Expand the following:
2 x (x + 5)
Hint: | Distribute 2 x over x + 5.
2 x (x + 5) = 2 x×5 + 2 x x:
2 x×5 + 2 x x
Hint: | Multiply 2 and 5 together.
2×5 = 10:
10 x + 2 x x
Hint: | Combine products of like terms.
2 x x = 2 x^2:
Answer: 10 x + 2 x^2
Find the original price of a pair of gloves that is $16 after a 20% discount.
Answer:
original price was 64 dollars
Step-by-step explanation:
Answer:
$15.80
Step-by-step explanation:
20% of 16, or 1/5 of 16, is 3.2. So we subtract 3.2 from 16
16 - 3.2 = 15.8
So, in dollar form, it is $15.80
So the final cost of the pair of gloves is $15.80

What is the solution to the inequality shown?
2(x + 3) < 6 - x
Answer:
x = 0
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
2x+6<−x+6
Step 2: Add x to both sides.
2x+6+x<−x+6+x
3x+6<6
Step 3: Subtract 6 from both sides.
3x+6−6<6−6
3x<0
Step 4: Divide both sides by 3.
3/3 < 0 /3
x = 0
4. There are 18 000 seats in Rogers Arena in Vancouver. At a sold-out Canucks game, there are 5 Canucks fans for every Flames fan.
a. What is the ratio of Canucks fans to Flames fans?

Answer: 5:1, 1:6, 15,000.
Step-by-step explanation:
a. logic
b.5+1
c. 18000 divided by 6 is 3000 so you subtract 3000 from the total which is 18000.
Quadrilateral BCDE is inscribed in circle A. The measure of ⏜ is 73°. The measure of ⏜ is 53° and the measure of ⏜ is 102°.
Determine the measure of ∠ BCD.
Answer:
117
Step-by-step explanation:
Angle BCD intercepted arc is Arc DEB.
We know DE measure but we need to find EB measure.
Since a circle circumference add up to 360, we can add all of the known arcs up to 360 to find the missing arc.
[tex]73 + 53 + 102 + x = 360[/tex]
[tex]126 + 102 + x = 360[/tex]
[tex]228 + x = 360[/tex]
[tex]x = 132[/tex]
So arc EB measure 132.
Arc eb and de.
132+102=234.
Angle BCD is inscribed angle of Arc DEB, so that means angle BCD is half of Arc DEB.
[tex] \frac{234}{2} = 117[/tex]

Identify the vertex of the parabola and tell whether it is a minimum or a maximum.
Answer:
First parabola's vertex is (-2,2), which is a minimum.
Second parabola's vertex is (3,2), which is a maximum.
Step-by-step explanation:
Simply, a vertex of a quadratic is a graph's turning point.
The maximum and minimum can be identified by seeing if the graph curves up or down.
Maximum occurs when your graph is facing down.
Minimum occurs when your graph is facing up.

Creating a Pythagorean Triple
Tess created a Pythagorean triple of (24, 32, 40) by multiplying the known Pythagorean triple 3, 4, and 5 by 8. Is Tess
correct? Can a Pythagorean triple be created using multiplies of a known Pythagorean triple.
O Yes, as long as each number in the Pythagorean triple is multiplied by the same whole number.
O Yes, as long as each number in the Pythagorean triple is multiplied by a different whole number.
O No, Pythagorean triples only exist with small numbers.
O No, multiplying a known Pythagorean triple by a whole number will not create a Pythagorean triple.

Answer:
2x^2(root13)
Step-by-step explanation:
52 factors into 13 (prime number) and 4 (perfect sqare)
this means we can take the root of 4 and bring it outside to become a 2
x^4 is a perfect square and is x^2 squared.
so then we have a 2 and x^2 on the outside and a 13 on the inside.

4. For which of the following probability assignments are events A and B independent?
P(AN B“) – 0.3. P(AN B) = 0.12, and P(Aºn B) = 0.4.
B
P(An BC) = 0.3. P(An B) = 0.3, and P(Aºn B) = 0.3.
C) P(An Bº) = 0.1. P(ANB) = 0.1, and P(Aº n B) = 0.4.
P(An Bº) = 0.3. P (AnB) = 0.0, and P(
AB) = 0.2.
E) P(An Bº) = 0.5, P (ANB) = 0.1 and P (Aºn B) = 0.4
Answer:
A
Step-by-step explanation:
formatting is so bad lol
but yeah its the first one because for independent events, the probably of a and b is the product of both probabilities, just like how 0.3*0.4=0.12
Given the equation y= -3x + 2.5 . When y is 8.5 , what value of x makes the equation true?
Answer:
x = -2
Step-by-step explanation:
y = -3x + 2.5
if y = 8.5 then:
8.5 = -3x + 2.5
-3x = 6
x = -2

sin 0 = 12/37 find tan 0
Answer:
sin α = 12/37
apply Pythagoras theorem,
Let get unknown side =y
12^2 + y^2 = 37^2
y^2 = 37^2 -12^2
y^2 = 1225
y = sqrt(1225)
y = 35
so, cos α = 35/37
