Answer #1- Add the expressions.  3x^2+2x−5+(−4+7x^2), Remove unnecessary parentheses.  3x^2+2x−5−4+7x^2, Add  3x^2 and 7x^2. 10x^2+2x−5−4, Subtract  4  from  −5. 10x^2+2x−9.

Final Answer: 10x^2  +2x−9 hopefully you now get an understanding of how to do it.

Answer #2: 7x−9

Answer #3: 4(11x+5)

Answer #4: 15x-1

Answer #5: 22x-9

Answer: Food Saver

Step-by-step explanation:

A 5-pound bag at Bargain Mart costs $6.45. The coat per pound will be:

= $6.45 / 5

= $1.29

A 2-pound bag at Food Saver costs $2.50. The cost per pound will be:

= $2.50 / 2

= $1.25

A 7-pound bag at Grocery Surplus costs $9.45. The cost per pound will be:

= $9.45 / 7

= $1.35

A 10-pound bag at Economart costs $12.89. ​The cost ​per pound will be:

= $12.89 / 10

= $1.289

Therefore, the shop which sells flour for the lowest unit price is Food Saver.

The perimeter of a patio is 64 feet. The width of the patio is 12 feet and the length of the patio is ( ) x + 6 feet. What is th
evablogger [386]
20 feet, 12+12+L+L=64 so you simplify and it becomes 24+L+L=64. Take away 24 from 64 and you get 40. 40 divided by 2 equals 20, and you can plug 20 into the L spots and it all works.

RQ is tangent to Circle S. Use the diagram below to find the measure of QRS. mQRS < 90 mQRS > 90 mQRS = 90 not enough info
Masteriza [31]
Given that you did not include the diagram showing the circle, the tangent line and the points Q, R, and S, I am going to give you the explanation to answer the question.

1) The tangent lines to a circle form a 90° angle with the radius at the point of intersection.

2) Therefore, if the point of intersection of the tangent line and the circle is named R, and the points S and Q are one the center of the circle and the other is on the line RQ, then you know that the segment SR is a radius and the line RQ is the tangent, which means that they are perpendicular, i.e. the angle QRS is measures 90°.

In this case the answer is m angle QRS = 90°.

3) Otherwise the angle is different to 90° and you need to observe the figure to conclude whether it is greater than 90°, less than 90° or there is not enough information.
