Answer:

H=80

Step-by-step explanation:

Step-by-step explanation:

i believe what you need help on is simplifying the equations. so let's start with the first one.

====================================================================

(2x+1)(x+5) original problem

(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.

2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.

2x2+11x+5 this is the most simplified equation.

====================================================================

6x−4xy original problem.

unlike the last problem, we can easily just... 6x + (−4xy).

−4xy+6x this is the most simplified equation.

====================================================================

ok, the last one. phew!

unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.

if we factored, we would get...

(4x+5)(4x−5)

===================================================================

Answer:

D. Henry's balloon was further from town at the beginning, but Tash's balloon traveled more quickly.

Step-by-step explanation:

With the lack of information provided, I was able to create a base and general observation and create an equation based off everything I know and believe. (may not be accurate due to lack of information and background on assignment and curriculum)

TASHA: y = 7x + 15

(current distance) = (7 miles per hour) + (starting distance)

(29) = (14) + (15)

HENDRY: y = 6x + 25

(current distance = (6 miles per hour ) + (starting distance)

(37) = (12) + (25)

The correct statement is Gerard should have found the area of the square, 36 cm², and added it to the area of the triangle, 10.5 cm², to get 46.5 sq. cm.

Area of a geometrical shape or figure in two dimension is the space which lies within the boundary of the shape.

The given composite figure composed of a triangle and a square.

So, we should find the area of both the triangle and the square and add it to get the area of the composite figure.

Let A₁ and A₂ be the area of the square and area of the triangle respectively.

Area of a square with side lengths 'a' = a²

Here, length of the side of the square = 6 cm

A₁ = 6² = 36 cm²

Area of a triangle with base 'b' and height 'h' = [tex]\frac{1}{2}[/tex] × b × h

Here, b = 6 cm and h = 3.5 cm

A₂ =  [tex]\frac{1}{2}[/tex] × 6 × 3.5 = 10.5 cm²

Area of the composite figure = A₁ + A₂

                                                =  36 cm² + 10.5 cm²

                                                = 46.5 cm²

Hence Gerard could have found the correct answer by finding the area of the square as 36 cm², and adding it to the area of the triangle, 10.5 cm², to get the area of the figure as 46.5 cm².

Answer:

The inequality on the number line shown is {x:x<2}

The inequality shown on the number line is represented by the relation x<2.

As,  the inequality on a number line, the notation includes the open circle at 2.

This means that the value of 2 itself is not included in the set of solutions.

In the notation "x < 2," the symbol "<" indicates "less than," and the number 2 is the upper bound of the inequality.

Since the inequality is strict, use an open circle to show that the point 2 is not part of the solution set.

Therefore, the inequality is "x < 2".

Answer:

Step 1: Create an Equation Using the idea (Angle B + Angle C = 180°)

=> 14x + x = 180°

Step 2: Solve.

=> 14x + x = 180°

=> 15x = 180°

=> x = 12°

Step 3: Multiply 12 by 14.

=> 12 x 14 = 168°

Step 4: Subtract 168 by 12.

=> 168 - 12

=> 156°

Final Answer:

After working on this problem, we can conclude that the difference between Angle B and Angle C is 156°

Answer:

y = -1/5 x -2

Step-by-step explanation:

Given line y = 5x - 1

as in slope intercept form m = 5

point (5, -3)

for two lines to be perpendicular product of slopes must be -1\

so for new line  slope is

m1 * m2 = -1

5 * m2 = -1

m2 = -1/5

line equation is y - (-3) = -1/5 (x - 5)

y + 3 = -1/5 x + 1

y = -1/5 x + 1 - 3

y = -1/5 x -2

Answer:

Step-by-step explanation:

Slope of the ⊥ line is ( - [tex]\frac{1}{5}[/tex] )

y - ( - 3 ) = - [tex]\frac{1}{5}[/tex] ( x - 5 )

y + 3 = - [tex]\frac{1}{5}[/tex] x + 1

y = - [tex]\frac{1}{5}[/tex] x - 2
