Hi there!

[tex]\large\boxed{(2x + 3)(x + 1)}[/tex]

We can split into factors using the "guess and check" method.

Factors are in the format of:

(ax + b)(cx + d), where in this instance:

a · c = 2

bc + da = 5

b · d = 3

Thus, we get:

(2x + 3)(x + 1)

Answer:

2x^2 +5x +3            3*2 =6  and 3+2 = 5

2x2 +2x +3x +3

2x(x +1) + 3(x+1)

(x+1)(2x+3)

Step-by-step explanation:

Answer:

option A is correct answer

One is given the following information:

One property of an isosceles triangle is the base angles theorem. This states that in an isosceles triangle, the two angles that are opposite the congruent sides are also congruent. Applying this theorem here, one can state the following:

[tex]AB = AC\\\\m<C = m<B[/tex]

The sum of angle measures in a triangle is (180) degrees. One can apply this here by stating the following:

[tex]m<A+m<B+m<C=180[/tex]

Substitute in the proved information: express angle (<C) in terms of angle (<B).

[tex]m<A+m<B+m<C=180[/tex]

[tex]m<A+m<B+m<B=180[/tex]

Simplify, combine like terms.

[tex]m<A+m<B+m<B=180[/tex]

[tex]m<A+2(m<B)=180[/tex]

Inverse operations: solve for angle (<B)

[tex]m<A+2(m<B)=180[/tex]

[tex]2(m<B)=180-(m<A)[/tex]

[tex]m<B=\frac{180-(m<A)}{2}[/tex]

Simplify,

[tex]m<B=\frac{180-(m<A)}{2}[/tex]

[tex]m<B=90-\frac{(m<A)}{2}[/tex]

Thus, one has proven that the statement ([tex]m<B=90-\frac{(m<A)}{2}[/tex]) is true.

Please note, this proof can be typed in a statement-reason format, where the bolded part of the written words above the statement is the reason.

Answer:

[tex]a. \: \: x = 3 \: \: and \: 5[/tex]

Step-by-step explanation:

[tex]a. \: \: \: x^2-8x+ 15 = 0 \\ {x}^{2} - 5x - 3x + 15 = 0 \\ x(x - 5) - 3(x - 5) = 0 \\ (x - 3)(x - 5) = 0 \\ x = 3 \: and \: 5[/tex]

[tex]b. \: \: 2x^2 - 5x - 6 =0 \\ x = \frac{5± \sqrt{73} }{4} [/tex]

Answer:

3 = - 4g - 5

3 + 5 = - 4g

8 = - 4g

8/-4 = g

-2 = g

* g = -2

The value of g in the equation 3= −4g −5 is -2.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 3=-4g-5

Three equal to minus four times of g minus five.

The g in the equation is a variable.

The operator in the given equation is Subtraction which is minus.

We need to find the value of variable g.

By addition property add 5 on both sides

3+5= −4g −5+5

The plus five and minus five will be cancelled in the right side.

3+5=-4g

Add 3 and 5 in left side.

8=-4g

By division property divide both sides by 4

g=-2

Hence, the value of g in the equation 3= −4g −5 is -2.

Answer:

please perimeter is a summation .

so how can the perimeter be 60^2?

Answer:

Angle 1 is 22°

Angle 2 is 78°

Step-by-step explanation:

Angles on a straight line always add up to 180°.

To find Angle 2, you would have to do 180° take away 102°.

180-102=78°

Angles in a triangle also add up to 180°.

So to find Angle 1, you would have to add the two Angles you already have and take it away from 180°.

80+78=158°

180-158=22°

Answer:

17 hours

Step-by-step explanation:

total cost = fee + cost per hour * hours

100 = 15 + 5h

Subtract 15 from each side

100-15 = 5h

85 = 5h

Divide by 5

85/5 = 5h/5

17 =h

Answer:

Kim rent the bike for 17 hours.

Step-by-step explanation:

h=hours

15 + 5h = 100

Subtract 15 on both sides.

5h = 85

Divide 5 on both sides.

h = 17

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Step-by-step explanation:

A because the amount of ice cream sales doesn't relate to the number of births in a city.

B works because amount of ice cream sales can relate to money. Both C and D work because temperature could affect when people want to buy ice cream. (people most likely won't buy ice cream in the winter but most likely will in the summer)

Answer:

x = measure of the first angle

2x -5 = measure of the second angle

3x - 19 = measure of the third angle

the sum of the measures of a triangle is 180 degrees

x + (2x-5) + (3x-19) = 180

6x - 18 = 180

x = 33 (first angle)

2x - 5 = 2 (33) -5 = 61 (second angle)

3x - 19 = 3 (33) - 19 = 86 (third angle)

Step-by-step explanation:

Statement A is an example of inductive statement, whereas, statement B is a example of deductive statement.

Inductive reasoning is a method of reasoning in which a body of observations is considered to derive a general principle. It consists of making broad generalizations based on specific observations.

For example,

The last few times I’ve driven past the beach on a sunny day, the parking lot was nearly full. Therefore, on sunny days, the beach parking lot will be nearly full.

Deductive reasoning is the mental process of drawing deductive inferences. An inference is deductively valid if its conclusion follows logically from its premises, i.e. if it is impossible for the premises to be true and the conclusion to be false.

For example,

On Thursdays, the trash gets picked up at the curb of the driveway. Today is Thursday. Therefore, the trash will get picked up at the curb of the driveway today.
