L. The width, w, of the rectangle is 10 inches. What is the perimeter of the rectangle?

1 answer:

8 0

40 inches because a rectangle has 2 sets of parallel lines and if the width and length are 10 then you just have to add up all the sides.

The length of a rectangle is 8 feet more than it's width. The area of the rectangle is 84 square feet. Find it's length and widt

S_A_V [24]

Length of the rectangle is 14 ft and width is 6 ft

Step-by-step explanation:

Step 1: Let the width of the rectangle be x, then length = 8 + x. Find dimensions if area = 84 ft²

⇒ Area of the rectangle = length × width

⇒ 84 = x(8 + x) = 8x + x²

⇒ x² + 8x - 84 = 0

⇒ x² + 14x - 6x - 84 = 0 (Using product sum rule to factorize)

⇒ x(x + 14) - 6(x + 14) = 0

⇒ (x + 14)(x - 6) = 0

⇒ x = -14, +6 (negative value is neglected)

∴ x = 6 and x + 8 = 14

Which system of linear equations appears to have a solution of (-1, 4)?

anyanavicka [17]

Answer:D

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

A solution is (-1,4) means that point of intercept is (-1,4)

<=> when x=-1 so y = 4 for both equations

From the 4 possible answers, only graph D meets the requirement.

Hope it will find you well
