2 answers:

8 0

7-2(2+5)-8
7-2(7)-8
5(7)-8
When there is a bracket it means, you are supposed to multiply the number in front of it with the number in the bracket. So....
5 x 7 -8= 35-8
= 27

Thus the answer is 27

Step-by-step explanation:

Area of the warehouse $=60,000$ ft^2$

Let the length of the warehouse=l

The warehouse's width is exactly $\dfrac23$ of its length

Therefore: Width of the warehouse $=\dfrac23l$

Area =Length X Width

Therefore:

$\dfrac23l*l=60000\\$Cross multiply\\2l^2=60000*3\\2l^2=180000\\$Divide both sides by 2\\2l^2 \div 2=180000 \div 2\\l^2=90000\\l^2=300^2\\$Length, l=300 feet\\Recall: Width =\dfrac23l\\$Therefore, Width of the warehouse=\dfrac23*300=200$ feet$
