sashaice [31]

The square root of 9 is $\sqrt{81}$
The square root of 10 is $\sqrt{100}$
If $\sqrt{n}$ = 9 to 10
then $\sqrt{n}$ = $\sqrt{81}$ to $\sqrt{100}$

The perimeter of the triangle below is 6a+2b-5 units. write an expression to represent the length in units, of the missing side

ANTONII [103]

Answer:

3a + 5b - 2

Step-by-step explanation:

The perimeter is the sum of all 3 sides of the triangle.

To find the missing side (x ) sum the 2 known sides and subtract from the perimeter.

x = 6a + 2b - 5 - (2a + 6b - 6 + a - 9b + 3 ) ← simplify parenthesis

= 6a + 2b - 5 - (3a - 3b - 3 ) ← distribute by - 1

= 6a + 2b - 5 - 3a + 3b + 3 ← collect like terms

= 3a + 5b - 2 ← length of missing side

Find the area of the shaded region of the square.

marishachu [46]

Answer:

42 $cm^{2}$

Step-by-step explanation:

area of the square=14*14(l*w)

=196 $cm^{2}$

radius=14/2

=7 cm

area of the circle= $\pi r^{2}$

= $\frac{22}{7}$ *7*7

=154 $cm^{2}$

area of the shaded part =196-154

= 42 $cm^{2}$
