A) x² + 7x - 12 is NOT equivalent to the expression.
Step-by-step explanation:
1) expand by distributing terms.
[tex] {x }^{2} - 3x + 4(x - 3)[/tex]
2) Expand by distributing terms.
[tex] {x}^{2} - 3x + 4x - 12[/tex]
3) Collect like terms.
[tex] {x}^{2} + ( - 3x + 4x) - 12[/tex]
4) Simplify.
[tex] {x}^{2} + x - 12[/tex]
The second equation are equivalent to the equation. but the first equation is not equivalent to the main equation.

Figure ABCD is a rectangle. In rectangles, opposite sides are equal. In the figure, BC and AD are opposite of each other, therefore their side lengths are equal. The side lengths are given: BC=9x-6, and AD=3x+12. Write this as an equation:
9x-6=3x+129x-3x-6=3x-3x+12 (Subtract 3x from each side of the equation)6x-6=12 6x-6+6=12+6 (Add 6 to each side of the equation)6x=18x=3 (Divide each side by 6)please let me know if this is wrong, hope it helps :)

Find the measure of the arc.

146°

B
MABC = [ ? 1°
Answers
Answer:
i get mABC = 270°
Step-by-step explanation:
This is fairly straight forward once you the right angle symbol for the arc AC. Also realizing the 148° for mAB is not needed for this question. The 148° for mAB would be useful if you wanted to calculate arc mBC.
Remember there are 360° in a circle.
The arc mAC is 90°
The arc mABC is the rest of the circle. is the arc from A to B to C
arc ABC + arc AC is the full circle 360°
mABC + mAC = 360° mAC = 90°
mABC + 90° = 360° - 90° from both sides
mABC = 360° - 90°
mABC = 270°
The angle ∠ABC in the given circle will be 270°.
What is an angle?
An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
Angle is very useful to measure any angular rotational motion for example if you have to find out the rotation among the circle then it cannot measure in length parameter such that meter inch so it will be measured as an angle in a unit of degree or radian.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Now since we know that the angle of complete rotation is 360°.
Now ∠ADC + ∠ABC = 360
Given that ∠ADC = 90°
∠ABC = 360° - 90° = 270°
Hence, 270° will be the correct answer.

Answer: 1430 girls
Step-by-step explanation:
In order to solve this we must take it step by step. So first things first. There are 12,481 people at this concert. If 8906 are adults we need to subtract to find out how many children there are. 12481-8906=3575. There are 3,575 children at this concert. Now if 3/5 of the children are boys then the other missing 2/5 must be the girls. There are a couple of ways to solve this but im going to go the direct route. multiply 3/5 by 3,575 to get 2,145 boys. Now if 2,145 out of 3,575 are boys then 3575-2145= 1430 girls
Let's sum up what we learned
1. 12,481 people are at a concert
2. 8906 adults are at this concert
3. 3,575 are children
4. 2145 are boys
5. Which means there are 1430 girls

Y=3x-2
Answers
Answer: -8, -5, -2, 1, 4
Step-by-step explanation:
Y=3x-2
- Plug in the number for x.
x = -2, y = 3x - 2= 3(-2) - 2 = - 6 - 2= - 8
x = -1, y = 3x - 2= 3(-1) - 2 = - 3 - 2= - 5
x = 0, y = 3x - 2= 3(0) - 2 = 0- 2= - 2
x = 1, y = 3x - 2= 3(1) - 2 = 3 - 2= 1
x = 2, y = 3x - 2= 3(2) - 2 = 6 - 2= 4

Answers
Answer:
x = 20
Step-by-step explanation:
You can solve this problem using similar triangles; you know the triangles are similar due to the AAA property because of the Corresponding Angles Theorem.
To find x, you need to identify what sides 8 and x correspond to:
8 corresponds to 14 (6 + 8)
x corresponds to (x + 15)
Now, you need to find the scale factor by dividing 14 by 8:
14 ÷ 8 = 7/4
At this point, you can write and solve an equation for x:
7/4x = x + 15
3/4x = 15 (subtract x from both sides)
x = 20 (multiply both sides by 3/4)

Answers
Answer:
4 times
Step-by-step explanation:
Given that :
Cups of liquid required = 2 2/3
Fraction of liquid cup added per 10 minutes = 2/3
The number of times 2/3 cups of liquid is added :
Total cups of liquid required / amount of liquid added at a time
2 2/3 ÷ 2/3
8/3 ÷ 2/3
8/3 * 3/2
