Answer:

6x^2 - 10x inches ^2

Step-by-step explanation:

The area of a rectangle is

A = l*w

= (3x-5) * (2x)

= 6x^2 - 10x

Answer:

The area of the rectangle is 6x^2(squared)-10x

Step-by-step explanation:

To find the area of rectangles, you must multiply the length by the width. The formst for this is A=LxW. When you substitute each part of the equation in, it becomes 2x(3x-5). When you have parentheses, distribute the number on the outside to each number(or variable) on the inside. First, multiply 2x by 3x. This leaves you with 6x^2(squared). Then, multiply the 2x by the -5. This leaves you with -10x. Combine each part to get 6x^2(squared)-10x. :)

Jonah is going to the store to buy candles for his igloo. Small candles cost $3.50 and large candles cost $5.00. He needs to buy

Semmy [17]

Answer:

$x+y\geq 20$

$3.50x+5.00y\leq 80$

Step-by-step explanation:

Let x represent number of small candles and y represent number of large candles.

We have been given that Jonah needs to buy at least 20 candles. This means number of small and large candles should be greater than or equal to 20. We can represent this information in an inequality as:

$x+y\geq 20...(1)$

We are also told that small candles cost $3.50, so cost of x small candles would be $3.50x$ .

Since large candles cost $5.00, so cost of y large candles would be $5.00y$ .

We are told that Jonah cannot spend more than $80, this means cost of x small candles and y large candles should be less than or equal to $80. We can represent this information in an inequality as:

$3.50x+5.00y\geq 80$

Therefore, our required system of inequalities would be:

$x+y\geq 20$

$3.50x+5.00y\leq 80$

A.) Find the product (-1.15) x 3.2 b.) Explain in words HOW you determined the sign of your answer.

Deffense [45]

(A)

we are given

(-1.15) x 3.2

Since, sign of 1.15 is negative

and sign of 3.2 is positive

so, we put negative sign in front

$(-1.15)*(3.2)=-(1.15*3.2)$

now, we can multiply them

and we get

$(-1.15)*(3.2)=-3.68$ .............Answer

(B)

Suppose, we are given product of two numbers 'a' and 'b'

so, we use this property

case-1: When both positive , then we put positive in front

$a*b=+(a*b)$

case-2: When both negative , then we put positive in front

$-a*-b=+(a*b)$

case-3: When first is negative and second is positive , then we put negative in front

$-a*b=-(a*b)$

case-4: When first is positive and second is negative , then we put negative in front

$a*-b=-(a*b)$

What is m∠A ? Enter your answer in the box. ° Triangles A B E and D C E share vertex E. Angle B is 18 degrees. Angle C is 43 deg

Allisa [31]

Answer: The measure of angle A is 60 degree.

Explanation:

It is given that the Triangles A B E and D C E share vertex E. Angle B is 18 degrees. Angle C is 43 degrees. Angle D is 35 degrees.

According to angle sum property, the sum of angles of a triangle is always 180 degree.

In triangle CDE,

$\angle ECD+\angle CDE+\angle DEC=180^{\circ}$

$43^{\circ}+35^{\circ}+\angle DEC=180^{\circ}$

$78^{\circ}+\angle DEC=180^{\circ}$

$\angle DEC=180^{\circ}-78^{\circ}$

$\angle DEC=102^{\circ}$

According to opposite vertical angle property.

$\angle AEB=\angle DEC$

$\angle AEB=102^{\circ}$

Use angle sum property is triangle ABE.

$\angle ABE+\angle BEA+\angle EAB=180^{\circ}$

$\angle ABE+102^{\circ}+18^{\circ}=180^{\circ}$

$\angle ABE+120^{\circ}=180^{\circ}$

$\angle ABE=60^{\circ}$

Therefore, the measure of angle A is 60 degree.
