Factor by gcf 6x2+3x+21 The 2 is supposed to be small.
Given:
The expression is:
[tex]6x^2+3x+21[/tex]
To find:
The factor of the given expression by GCF.
Solution:
It is given that,
[tex]6x^2+3x+21[/tex]
The terms of the given expression are [tex]6x^2,3x,21[/tex]. The greatest common factor of these terms is 3.
[tex]6x^2+3x+21=3\times 2x^2+3\times x+3\times 7[/tex]
So, taking out the GCF, the given expression can be rewritten as:
[tex]6x^2+3x+21=3(2x^2+x+7)[/tex]
Therefore, the factor form of the given expression by GCF is [tex]3(2x^2+x+7)[/tex].

find the value of x on both problems please help this is urgent and please show work
Answer:
Step-by-step explanation:
1) the triangle is right, so we can use the Pythagorean theorem
x^2 + 24^2 = (16+x)^2
x^2 + 576 = x^2 + 256 + 32x
32x = 320
x = 10
2) the two segment are congruent, so
7x - 13 = 9x - 23
2x = 10
x = 5

2B, rounded to the nearest degree. Please help me
Answer:
∠ B ≈ 53°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan B = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{4}{3}[/tex] , then
∠ B = [tex]tan^{-1}[/tex] ([tex]\frac{4}{3}[/tex] ) ≈ 53° ( to the nearest degree )

What is the length of the longest side ?
Answer:
11 feet (Option C)
Step-by-step explanation:
Let the longer side be l and the shorter side be b.
We know that,
→ Perimeter of rectangle = 2 ( longer side + shorter side )
Here,
Perimeter of rectangle is 32 feet.→ 32 = 2 (l + b)
→ 32 = 2l + 2(5)
→ 32 = 2l + 10
→ 32 - 10 = 2l
→ 22 = 2l
→ [tex] \sf \dfrac{22}{2} [/tex] = l
→ 11 = l
→ 11 feet = longer side
[tex] \therefore [/tex] Length of the longer side is 11 feet.

At the Middleton School festival, a tent covers a rectangular space 30 1/2 yards long and 9 1/3 yards wide. What is the area, in square yards, covered by the tent?
Answer:
284 2/3 square yardsStep-by-step explanation:
Area of rectangle:
A = lwA = 30 1/2 * 9 1/3 = 61/2 * 28/3 = 854/ 3 = 284 2/3 square yardsAnswer:
284 ²/₃ square yards
Step-by-step explanation:
Area of a rectangle
Area = length × width
Given:
length = 30 ¹/₂ yardswidth = 9 ¹/₃ yardsSubstitute the given values into the formula and solve for area:
[tex]\begin{aligned}\sf Area & = \left(30+\dfrac{1}{2}\right) \times \left(9+\dfrac{1}{3}\right)\\\\ & = \dfrac{30 \times2+1}{2} \times \dfrac{9 \times 3+1}{3}\\\\ & = \dfrac{61}{2} \times \dfrac{28}{3}\\\\& = \dfrac{61 \times 28}{2 \times 3}\\\\ & = \dfrac{1708}{6}\\\\ & = \dfrac{1704+4}{6}\\\\ & = \dfrac{1704}{6}+\dfrac{4}{6}\\\\ & =284\: \frac{2}{3}\:\:\sf square\:yards\end{aligned}[/tex]
Therefore, the area covered by the tent is 284 ²/₃ square yards.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
y=-16x^2+147x+80
Answer:
t = 9.7 seconds
Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation as :
[tex]y=-16x^2+147x+80[/tex]
We need to find the time that the rocket will hit the ground, to the nearest 100th of second.
When the rocket hit the ground, So,
[tex]-16x^2+147x+80=0\\\\x=-0.515\ s\ and\ 9.70\ s[/tex]
Neglecting negative tim,
t = 9.7 s
Hence, it will hit the ground at 9.7 seconds.
Tiles with the numbers 1 through 9 are placed in a bag. What is the probability of choosing an even number that is greater than or equal to 4?
have anyone figured it out yet? pleaseee i need answer
The probability of choosing an even number that is greater than or equal to 4 is 0.3333 or 33.33%.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Tiles with the numbers 1 through 9 are placed in a bag.
The total outcomes will be
Total outcome = 9 {1, 2, 3, 4, 5, 6, 7, 8, 9}
The probability of choosing an even number that is greater than or equal to 4 will be
Favorable event = 3 {4, 6, 8}
Then the probability will be
[tex]\rm P = \dfrac{3}{9}\\\\P = 0.3333\\\\P = 33.33 \%[/tex]
