There are 6 rectangular flower gardens each measuring 18 feet by 17 feet in a rectangular city park measuring 80 feet by 160 fee
Aneli [31]

The area which is not in used for the flower gardens is 10964 sq ft.

Step-by-step explanation:

Given,

Length (l) of the rectangular park = 160 ft

Width (b) of the rectangular park = 80 ft

Length (l) of each rectangular flower garden = 18 ft

Width (b) of each rectangular flower garden = 17 ft

To find the area which is not in used.

Formula

The area of rectangle = l×b

Now,

The area of the rectangular park = 160×80 sq ft = 12800 sq ft

The area of each rectangular flower garden = 18×17 sq ft = 306 sq ft

The area of 6 rectangular flower garden =  306×6 sq ft = 1836 sq ft

So,

The area which is not in used = 12800-1836 sq ft = 10964 sq ft.

Ali simplifies the expression 9y+y to 9y2. Use the drop-down menus to complete the statements below to explain why Ali's solutio
maxonik [38]

Ali's solution is incorrect.

Ali had to add both the terms and should get 10y answer, and not multiply both terms and get answer 9y^2 which is wrong.

Step-by-step explanation:

Ali simplifies the expression 9y+y to 9y2. We need to identify if Ali's solution is correct or incorrect.

Ali's solution is incorrect.

Reason:

We are given the expression: 9y+y

When we add two like terms ( terms having the same variable and exponent), we add the coefficients of both like terms.

In our case 9y+y = 10y

Whereas Ali has done multiplication of both terms and not addition.

In multiplication we add the exponents of the same variables i.e 9y+y = 9y^2

So, Ali had to add both the terms and should get 10y answer, and not multiply both terms and get answer 9y^2 which is wrong.
