A rectangle is 8 feet long. Its width is represented by "seven plus x feet." Which expression represents the area, in square fee

Sauron [17]

Answer:

$\boxed{\sf Area \ of \ the \ rectangle = (8x + 56) \ square \ feet}$

Given:

Length = 8 feet

Width = (7 + x) feet

To find;

Area of the rectangle

Step-by-step explanation:

$\sf Area \: of \: the \: rectangle = Length \times Width \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 8 \times (7 + x)\\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = (8 \times 7) + (8 \times x)\\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 56 + 8x\\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = (8x + 56) \: square \: feet$

How would I do this? What would it be?

Vinvika [58]

50

Step-by-step explanation:

Since AE is the bisector of angle BAC,so angle BAE and Angle CAE is equal. Here Angle CAE and Angle EAC is same.

therefore,

m(Angle BAE)=m(Angle EAC)

$x + 30 = 3x - 10$

or, 2x=40

or, x=20

Hence,

m(Angle EAC)=

$3x - 10$

=

$(3 \times 20) - 10 = 60 - 10 = 50$

The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second numbe

professor190 [17]

Answer:

The equation that represents this solution is: 10+x= -18

The second number is -28.

Step-by-step explanation:

To solve for this, we first need to make an equation. We know that one of the numbers, the first one, is 10, but the second is unknown. Because of this, we will label the unknown number x. We also know that the -18 is the sum, so we know it will be behind the equal sign. Using this info, we can make the following equation.

10+x= -18

We did 10 because it was the first, added it with the unknown x, and it all equals -18. This would be your equation.

To find the answer, you need to solve the equation.

10+x= -18

First, since we are adding ten to both sides, subtract ten from both sides.

10-10+x= -18-10

Now, solve. Remember that subtracting a positive number is the same as adding a negative number.

x= -28

Now, check. Does 10+ -28 equal -18? Yes, so we are correct.

An isosceles triangle has base angles that each measure 39 °. Which equation can be used to fi nd t, the measure of the third an

Montano1993 [528]

Answer: 102°

Step-by-step explanation:

First and foremost, we should note that an isosceles triangle has two sides that are equal and that the sum of angles in a triangle equals to 180°.

Since we are told that the isosceles triangle has base angles that each measure 39°, the third angle will be:

t + 39° + 39° = 180°

t + 78° = 180°

t = 180° - 78°

t = 102°

The third angle is 102°.

Team tool Bella gathered 15 pounds of wood in 1/3 of an hour. What was their speed in pounds per hour.

allochka39001 [22]

Team tool Bella gathered 15 pounds of wood in 1/3 of an hour.

1/3 of an hour is equal to 1/3 of 60 mins = 1/3 * 60 mins = 20 mins

We have to find their speed in pounds per hour( 60 mins).

Pounds of woods gathered in 1 hour or 60 mins = 15/20*60

= 15 * 3

= 45 pounds

Therefore, their speed in pounds per hour is 45 pounds / hour

Hope this helps ..!!

Thank you :)
