Correct Answer:
[tex]x^2 + 7x + 12[/tex]
Step-by-step explanation:
The error that was made, is that they accidentally added 3 and 4 together, during the distribution, when they should have multiplied it, leaving them with 7 instead of 12.

Find the value of x. Write your answer in simplest form. need help quick pls
Answer:
The value of x is approximately 5
Step-by-step explanation:
Answer:
x=6.36
Step-by-step explanation:
In a right triangle where the angles are 45, 45 and 90, the hypotenuse is equal to [tex]\sqrt{2}[/tex] multiplied by the length of the legs. Knowing this, we can set up the following equation:
[tex]9=x\sqrt{2}[/tex]
Multiply both sides by [tex]\sqrt{2}[/tex]
[tex]9\sqrt{2} =x\sqrt{2}*\sqrt{2}\\9\sqrt{2} =2x[/tex]
Divide both sides by 2
[tex]\frac{9\sqrt{2}}{2}=\frac{2x}{2}\\\frac{9\sqrt{2}}{2}=x[/tex]
[tex]x=6.36[/tex] (this answer is approximate)
Therefore, x is equal to 6.36.

Answer:
x = 16
4x = 64
Step-by-step explanation:
The sum of the exterior angles of any polygon is 360°
Add the given angles and solve for x
93 + 46+ 3x + 62 + 4x +47 = 360
7x + 248 = 360
7x = 360 –248
x = 16
4(16) = 64

What is the area of this triangle?
A=bh2
a-54 cm²
b-90 cm²
c-108 m²
d-216 m²
Answer:
a
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 9 and h = 12 , then
A = [tex]\frac{1}{2}[/tex] × 9 × 12 = [tex]\frac{1}{2}[/tex] × 108 = 54 cm²

Which equation best represents the graph shown above?
Answer:
B
Step-by-step explanation:
Choose an x point. Then plug it in and see if you get the correct y.
For example, I chose an x point of -1. When x = -1, you can see that y = 4.
Plug it in to the equations, and you find that B is correct.
y (4) = [tex]x^{2}[/tex] (-1 x -1) - 2x ( 2 times -1) + 1
4 = 1 - (-2) + 1
4 = 1 + 2 + 1
4 = 4

Combine like terms. Your answer should contain decimals. 0.5(x4 − 9) + 15 = Please in 10 mins please
Answer:
x ≈ ±2.1407
Step-by-step explanation:
0.5(x⁴ - 9) + 15 = 0
Distribute the 0.5 across the parentheses.
0.5x⁴ - 4.5 + 15 = 0
Combine the constants.
0.5x⁴ + 10.5 = 0
Subtract 10.5 from both sides.
0.5x⁴ = -10.5
Divide both sides by 0.5.
x⁴ = 21
Take the fourth root of 21.
⁴√21 ≈ ±2.1407
x ≈ ±2.1407

A 36-foot long rope is tied from the top of a pole to a stake in the ground. If the stake is 17 feet from the base of the pole, find the height of the pole. Round to the nearest tenth if necessary.
Answer:
Perpendicular = 31.73 ft (Approx)
Step-by-step explanation:
Given:
Length of rope (Hypotenuse) = 36 ft
Base = 17 ft
Find:
Height of pole (Perpendicular)
Computation:
Perpendicular = √Hypotenuse² - Base²
Perpendicular = √36² - 17²
Perpendicular = √1,296 - 289
Perpendicular = 31.73 ft (Approx)
URGENT!!! A factory process requires 3 steps to finish a product. The steps each have a mean completion time of A= 10 seconds and a standard deviation of o = 5 seconds. The time it takes to complete each step is independent from the other steps. Let T be the total completion time for the 3 steps.
Find the standard deviation of T.
Choose 1 answer:
OT = 15 seconds
Or = 75 seconds
or 15 seconds
or = v75 seconds
Answer:
d
Step-by-step explanation:
The standard deviation of T is equivalent to 5.
What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.Mathematically, we can write -[tex]$\sigma={\sqrt {\frac {\sum(x_{i}-{\mu})^{2}}{N}}}[/tex]
Given is that a factory process requires 3 steps to finish a product. The steps each have a mean completion time of A = 10 seconds and a standard deviation of O = 5 seconds. The time it takes to complete each step is independent from the other steps.
We can write that -
5 = √∑(x{i} - 10)²/√3
√∑(x{i} - 10)² = 5√3
(√∑(x{i} - 10)²)² = (5√3)²
∑(x{i} - 10)² = 25 x 3
∑(x{i} - 10)² = 75
Now, we can write that -
σ = √(75/3)
σ = √25
σ = 5
Therefore, the standard deviation of T is equivalent to 5.
