Agroup of students is given a 10 by 10 grid to cut into individual unit squares. the challenge is to create two squares using all of the unit squares. their teacher states that after the two new squares are formed, one should have a side length two units greater than the other.

which equation represents x, the side length of the greater square?

x2 + (x – 2)2 = 10
x2 + 2x2 = 10
x2 + (x – 2)2 = 100
x2 + 2x2 = 100

Step-by-step explanation:

Given,

The measurement of the grid = 10 × 10

So, the area of the grid = 100 square unit,

Now let x be the side of larger square that is formed by the grid,

Thus, according to the question,

The side of smaller square = (x-2) unit,

Hence, we can write,

The area of square having side x + The area of square having side (x-2) = The total area covered by grid

Which is the required equation.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
