4d+20. Four d’s mean 4d or 4 times d. 5+5+5+5 is 20, so in expression form it would be 4d+20.

Group the d’s together and you would get 4d and then group the 5’s together and you get 20

Which equation results from taking the square root of both sides of (x + 9)2 = 25?

Alex_Xolod [135]

Answer:

√2.37+ 3 √9 = √5. 3 is the last one

x+9 =+25

Step-by-step explanation:

(x+9)2= 25 This means x= 3.5 and the square root of x = √3.5 = 1.87 square root of 9 x 2 = √18 =4.24

We can also see 18+7 =25

√5.65 √5

this is 25 = 5 so it's the last one.

as 2.37+ 3 √9 = √5. 3

A semi-circle window can be used above a doorway or as an accent window

anzhelika [568]

A semicircle is a part of a circle, and it is referred to as half of a given circle. Thud the area of the semi-circle window is 982 $in^{2}$ .

A circle is a shape that is bounded by a curved path which is referred to as the circumference. Some parts of a circle are radius, diameter, sector, arc, semi-circle, circumference, etc.

A semicircle is a part of a circle, and it is referred to as half of a given circle.

such that:

Area of a circle = $\pi$ $r^{2}$

and

area of a semicircle = $\frac{\pi r^{2} }{2}$

where: r is the radius of the circle, and $\pi$ is a constant with a value of $\frac{22}{7}$ .

Thus from the given question, it can be inferred that;

r = $\frac{50}{2}$

= 25

r = 25 in

Thus, the area of the semi-circle can be determined as;

area of the semi-circle = $\frac{1}{2}$ * $\frac{22}{7}$ * $25^{2}$

= 982.1429

area of the semi-circle = 982.14 $in^{2}$

The area of the semi-circle window is approximately 982 $in^{2}$ .
