1239892873467123298347. What method would you use to solve it, and why
would you pick that method? (please note: do NOT attempt to solve it)

Answer:

5x-10

Step-by-step explanation:

3x-4+2x-6

group like terms

3x+2x -4--6

5x-10

The expressions that are equivalent to 3x - 4 + 2x - 6 are:

5x - 2 - 6

5x - 16

To determine which expressions are equivalent to 3x - 4 + 2x - 6, we can simplify the given expression:

3x - 4 + 2x - 6

Combining like terms, we have:

(3x + 2x) + (-4 - 6)

Simplifying further:

5x - 10

Now, we can compare this simplified expression to the provided options:

a) 3x + 2x - 10

b) 5x - 2 - 6

c) 5x - 16

d) 6x - 10

By comparing the simplified expression 5x - 10 to the options, we find that options b) (5x - 2 - 6) and c) (5x - 16) are equivalent expressions.

Answer:

628ft²

Step-by-step explanation:

From the diagram, we are given the following

diameter of the semicircles

2semi circles  = 1 circle

Area of 2semicircles = πd²/4

Area of 2semicircles = 3.14(20)²/4

Area of 2semicircles = 3.14*400/4

Area of 2semicircles = 3.14*100

Area of 2semicircles = 314ft²

Area of the quarter circle =  πd²/4 * 1/4

Area of the quarter circle =  πd²/16

d = 2r

d = 2*20

d = 40ft

Area of the quarter circle  = 3.14(40)²/16

Area of the quarter circle = 3.14*1600/16

Area of the quarter circle = 3.14*100

Area of the quarter circle = 314ft²

Area of the fountain = 314ft²+314ft²

Area of the fountain = 628ft²

the answer is 6 at the top and 9 at the bottom but the answer for that question is 6.

Answer:

Length of smaller side = 15 inches

Length of bigger side = 36 inches

Length of hypotenuse = 39 inches

Step-by-step explanation:

Given:

Length of smaller side = a

Length of bigger side = (a + 21) inches

Length of hypotenuse = (a + 24) inches

Find:

Length of all side

Computation:

Using Pythagorean theorem

Hypotenuse² = Base² + Perpendicular²

(a+24)² = a² + (a+21)²

a² + 576 + 48a = a² + a² + 441 + 42a

a² - 6a - 135 = 0

(a-15)(a+7)

So

a = 15 inches a = -7 inches

So,

Length of smaller side = a = 15 inches

Length of bigger side = (a + 21) inches = 15 + 21 = 36 inches

Length of hypotenuse = (a + 24) inches = 15 + 24 = 39 inches

Answer:

Turbo jetpack = 6(d + 7)

Xray vision glasses = 2d - 5

Invisible shield = 10d + 1

18d + 38 ;

128 dozen accessories

Step-by-step explanation:

Let the number of boxes sold = d

Turbo jetpack = 6(d + 7)

Xray vision glasses = 2d - 5

Invisible shield = 10d + 1

Combined number of accessories sold :

6(d + 7) + (2d - 5) + (10d + 1)

6d + 42 + 2d - 5 + 10d + 1

18d + 38

If 5 dozens are sold

d = 5

Number of accessories sold :

18(5) + 38

90 + 38 = 128 dozens accessories

D. 4 • 1 = 4

Step-by-step explanation:

In Mathematics, we have two kinds of Identity property

a) Identity property of Addition

This means that when you add a number to zero, it gives you that same number

Example: 6 + 0 = 6

b) Identity property of Multiplication,

This means that, when a number is multiplied by 1, it gives that same number.

Example: 8 × 1 = 8

Therefore, from the above question, the equation that demonstrates identity property is 4 • 1 = 4

Answer:

1.4 Inches Each

Step-by-step explanation:

This problem is fairly simple. Just divide 7 by 5 and put the correct units(inches) with the answer.

length of licorice each student will get is 1.875 inches.

A mathematical expression gets simpler when it is transformed into an equivalent, frequently shorter statement. One strategy for promoting uniformity in job effort, cost, and time is procedure simplification. It lessens diversity and variation that is harmful, unwanted, or unneeded.

Given, A licorice rope is 7 inches long. If four 5th graders share the licorice equally amongst themselves.

Since every 5th grader is sharing the rope equally.

Thus everyone will get = 7/4

Every 5th grader will get = 1.875 inches

Therefore, every 5th grader will get 1.875 inches length of licorice.

Answer:

Step-by-step explanation:

A—>108m

B—>180m

M<B—> 59°

The side BC and AC and the angle B is 108 m,180 m and 59°.

A triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

[tex]\rm sin \theta = \frac{P}{H} \\\\ \rm sin 31^0= \frac{a}{210} \\\\ a=108 \ m[/tex]

[tex]\rm cos \theta = \frac{B}{H} \\\\ \rm cos 31^0 = \frac{b}{210} \\\\ b=180 \ m[/tex]

The measure of the angle of triangle is 180°

∠A+∠B+∠C=180°

31°+∠B+90°=180°

∠B=59°

Hence, the side BC and AC and the angle B is 108 m,180 m and 59°.

Answer:

tan51 = JL ÷ 14

JL = 17,29

cos72 = KL ÷ 17,29

KL = 5,34

From the given information JLK = 72°, JM = 14 and JML = 51°. The distance of KL is 5.34.

Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.

In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slanted side is called the hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.

It is given that

JLK = 72°

JM = 14

JML = 51°

tan51 = JL / 14

JL = 17.29

cos72 = KL / 17.29

KL = 5.34

In the given diagram, the value of x is 15

The Pythagorean theorem states that, in a right triangle, the square of the longest side (hypotenuse) equals sum of squares of the other two sides

From the question, we are to determine the value of x.

x is the radius of the circle

Recall: Radius is any line that runs from the center to any part of the circumference

Consider the right triangle formed, x is the hypotenuse

By the Pythagorean theorem,

x² = 9² + 12²

x² = 81 + 144

x² = 225

x = √225

x = 15

Hence, the value of x is 15.
