The distributive property to solve 3(x+2)
rewrite
3(x) + 3(2)
3x + 6
Which ever person solve it to this is correct ;)
Hope this helps :)
Answer:
This is the mixed number 2 & 1/4
whole part = 2
fractional part = 1/4
=======================================================
Explanation:
Each tickmark represents
If you count the spaces between points F and A, you should count out exactly 9 spaces as shown in the diagram below.
We'll multiply that value 9 by to get our final answer.
The result we get is a mixed number 2 & 1/4, meaning the whole part is 2 and the fractional part is
Answer:
A ≈ 8133.27 m²
Step-by-step explanation:
Sum the parts of the ratio 6 + 7 + 8 = 21 parts
Divide the perimeter by 21 to find the value of one part
420 ÷ 21 = 20 ← value of 1 part of the ratio, hence sides of triangle are
6 × 20 = 120
7 × 20 = 140
8 × 20 = 160
To calculate the area (A) we can use Hero's formula
A =
Where s is the semi perimeter and a, b, c the sides of the triangle
let a = 120, b = 140 , c = 160 and s = 420 ÷ 2 = 210
A =
=
= ≈ 8133.27 m²
5b - 6 = 24
5b - 6 + 6 = 24 + 6
5b = 30
5b/5 = 30/5
b = 6
Answer: <u><em>Problem 1</em></u>
SA = 430.0
Step-by-step explanation:
13*11=143 divided by 2 is 71.5 (front face of the figure)
13*11=143 divided by 2 is 71.5 (backk face of the figure)
13*7=91 (left side rectangle)
17*7=119 (right side face rectangle)
11*7=77 (base)
Add all together 71.5+71.5+91+119+77=430.0
<u><em>Problem 2</em></u>
10*9=90 divided by 2 = 45 (front face triangle)
10*9=90 divided by 2 = 45 (back face triangle)
10*9=90 (right side rectangle face)
10*13.5=135 (left back side rectangle face)
10*10=100 (base)
Add everything together
45+45+90+135+100=415.0
