Algebra 1 Honors Add Polynomials to find perimeter

Answers

Answer 1

Answer:

The perimeter of the quadrilateral is 4z 16.

What is Perimeter?

To calculate the perimeter, or distance around the rectangle, sum all four side lengths. This may be done quickly by adding the length and breadth and then multiplying the total by two because each side length has two lengths. The perimeter formula is perimeter=(length+width)2.

The 4 sides of quadrilateral is z-4.

Now, the Perimeter of quadrilateral

= (z-4) + (z-4) + (z-4) + (z-4)

= 4 (z-4)

= 4z- 16

Thus, the perimeter is 4z- 16.

Answer 2

Answer:

Answer:

4z-16 units

Step-by-step explanation:

$P=4S$

$S=z-4$

$P=4(z-4)$

$P=4z-16$

The perimeter of the rectangle is 4z-16 units.

Kendra makes $8 per hour mowing lawns in the summer. Gas for the mowercosts $16 and will last all summer. How many hours must she mow to earn at
least $200?

Answers

Answer:

27 hours

Step-by-step explanation:

So t is going to represent time. $8t is equivalent to how much she makes for t amount of time. Being she is already down $16 for the gas, we have to take that into consideration that she must earn that back. Set up:

$8t - $16 = $200

Add like terms to get:

$8t = $216

Now solve for t by dividing both sides by $8.

t = 27 hours

Which ordered pair is a solution of the equation? y=-2x+5y=−2x+5 (Choice A) A Only (2,-9)(2,−9) (Choice B) B Only (-2,9)(−2,9) (Choice C) C Both (2,-9)(2,−9) and (-2,9)(−2,9) (Choice D) D Neither

Answers

Answer:

Choice B: Only (-2, 9)

Step-by-step explanation:

Of the two choices, only the point (-2, 9) satisfies the equation:

... y = -2x +5

... 9 = -2(-2) +5 = 4 +5 = 9

Answer:

The correct answer is B. Only (-2,9) is a solution of the equation.

Step-by-step explanation:

To figure out if an ordered pair is a solution to an equation, you could perform a test.

Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

We have the equation

$y=-2x+5$

and two different ordered pairs (2, -9) and (-2, 9).

We use the x-value in the first ordered pair, x = 2, and we plug it into the equation.

$y=-2(2)+5\ny=-4+5\ny=1$

If we compare with the ordered pair (2, -9), y must be equal to -9, but when we plugged x = 2 into the equation, we obtained that y = 1, so this is not a solution.

Using the x-value of the second ordered pair, x = -2, we get

$y=-2(-2)+5\ny=4+5\ny=9$
