In triangle do pythogrean to find height 5 sq -3sq = 16 and sq rt of 16 is 4
So triangles are 1/2 bh 1/2 (3)4 = 6
One sale 5x5 one shape 5x4 one gape 3x5 plus two triangles
25+ 20+ 15 + 6+6= 72
Answer:
20000
Step-by-step explanation:
you do 5 plus 5 then add it to 10
then u get 200 which u times it by 100
Answer:
120 blocks total
Step-by-step explanation:
All of the little cubes have side length 2" Thus, the 11" height of the box cannot be used entirely: we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.
Start at the bottom of the box. The dimensions of the bottom are 12" by 8". Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide. We can add 3 more such rows to fill the available 8" width of the box bottom. That's 6*4, or 24 blocks.
We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.
5 layers times 24 blocks per layer comes to 120 blocks total.
This is all I understand
Part A. 4x+3x=7x
-5+9=4 Part a is 7x+4
Answer:
3, -11-3
Step-by-step explanation:
(3x+1\)^2-100=0
(3x+1)^2-100+100=0+10
(3x+1)^2=100
3x+1=sqrt{100}
3x+1=-sqrt{100}
