Answer:
-2x+-8-3x-8
Step-by-step explanation:
-2 times x =-2x
-2 times 4=-8
Peter answered 9 of the questions correctly. 15 divided by 100 to get .15 and then multiply by 60 to get 9. Got 9 correct, 7 incorrect.

Left border = 8 feet
Lower border =32 feet
Area=128 〖ft〗^2
<u>Explanation </u>
The area is a right triangle.
Let us take the left border to be y feet and the lower border to be x feet
Area=1/2 yx
The cost of fencing would be 4y+x=64.
From this expression x=64-4y
Substituting this value of x in the area we have;
Area=1/2 y(64-4y)
A=32y-2y^2
To get the maximum area of the triangle the first derivative of the area would te equal to zero.
A=32y-2y^2
dA/dy=32-4y=0
4y=32
y=8
Since x=64-4y
x=64-(4×8)=32
The dimensions of the garden are 8 feet by 32 feet.
Since the garden is a right triangle,
Area=1/2×8×32
Area=128 〖ft〗^2

Answer:
9
Step-by-step explanation:
60 requests are made.
Spencer gets 25% of these requests. Convert this to a decmal (divide by 100) to get 0.25. 25% of 60 is:
So Spencer gets 15 requests. Now do the same process for Tanvi:
So Tanvi gets 6 requests. To find out how many more requests Spencer gets compared to Tanvi:
Therefore, Spencer gets 9 more requests than Tanvi.
