7
Step-by-step explanation:
do 8.40 divided by 1.20 which gives you 7
you can double check by multiplying 1.20 by 7
We know that b
<span>⩾ 1, so b is never 0.
a)
notice, the first figure starts off with 4 tiles and has 10 bordering tiles.
the second figure starts off with 14 tiles and has 14 bordering tiles
the third figure has starts off with 28 tiles and has 20 bordering tiles.

Answer: #20, x = 3
#21, x = 1/2
Step-by-step explanation:
#20) x + 4 + x + 2+ x + 5 = x + 3 +x+3+x+1+x+1
3x + 11 = 4x + 8
<u>-3x -3x</u>
11= x + 8
<u> - 8 - 8</u>
3 = x
#21) 12x(5) = 6x + 9 + x + 10 + x + 7
60x =8x + 26
<u> -8x -8x</u>
52x = 26
divide both sides by 52
x = 1/2
The square base area is 6 x 6 = 36. Then each triangle is the same base and height. Formula for area is 1/2(b)(h). So, each triangle is 1/2(6)(12)=36. So all sides are 36x5=180 units squared.
Answer:
the slope is 3 and you can put points on (1,3) and (2,6) to demonstrate this in the graph
