Sharon has a piece of cloth of area 170 sq. cm; can she make a square handkerchief of length 12 cm

Yes

Step-by-step explanation:

First we have to get the area of the square when the length is 12cm. We know a square has equal sides so we can simply do l * l to get the area.

12 * 12 = 144.

Let's compare this to 170.

170 > 144, so yes we will have enough to make a 12 by 12 handkerchief :)

answer: the answer is ann

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
