17 x 2 = 34
54- 34 = 20
20/2 = 10 which is the width of the garden
17+5= 22
22 x 10= 220feet = the new area
Answer:
Step-by-step explanation:
<h3>(a)</h3>
The nearest squares to 220 are 14² = 196 and 15² = 225. Since 220 is closer to 225 than to 196, the nearest whole number to the square root of 220 is 15.
The square root of -220 is imaginary, so the nearest whole number value will be 15i.
__
<h3>(b)</h3>
The decimal fraction part of the root can be estimated from the nearest squares to be ...
(220 -196)/(225 -196) ≈ 0.828
Then the root of 220 to the nearest tenth is 14.8. The root of -220 to the nearest tenth will be the imaginary number 14.8i.

The mass of a thin triangular plate bounded by the coordinate axes is 3 3/4.
<h3>How to calculate the mass?</h3>
It should be noted that mass simply means a quantity of matter that's in a body. It's the meaure of the inertia in the body.
In this case, from the complete question, the mass will be:
= 3/1000[1/24x⁴ - 25x² + 1000/3x]
= 15/4
= 3 3/4

It is D
Because the amount of the inside angles of an triangle are equal to 180 degrees
And a straight line is 180 degrees
