x = 8
Solution:
Side-splitter theorem:
<em>If a line is parallel to one side of a triangle and the line intersects the other two sides, then this line divides those two sides proportionally.</em>
Do cross multiplication, we get
⇒ 4 × 42 = 21x
Divide by 21 on both sides, we get
⇒ 4 × 2 = x
⇒ 8 = x
Switch the sides.
⇒ x = 8
The value of x is 8.
Answer:
1 18/35
Step-by-step explanation:
I feel like #19 is cut off...
20. 72000000 = 7.2 x 10^7
if you do 72000000.0 and move the decimal to the left until the number is less than 10, it'll be 7 spaces.
Answer:
B. Solve s + 11 = 2s – 7 to find the value of s.
Answer:
<u>144</u>
Step-by-step explanation:
Ok. I love problems like this.
You just have to find the surface are of each part and add it up!
To find the surface area of a rectangle, you multiple the base and the height. To find the surface area of a triangle, you multiple the base and height, and divide by 2 (because its half of a rectangle).
<u>Left rectangle:</u> 3*ll=33
<u>Middle rectangle:</u> 4*ll=44
<u>Right rectangle:</u> 5*ll=55
<u>Top triangle:</u> 3*4=12
12/2=6
<u>Bottom triangle:</u> 3*4=12
12/2=6
<u>ADD THEM ALL!!!</u> 33+44+55+6+6=<u>144</u>
