(2x^2-x^2)= x^2
(1+7) = 8
X^2 + 8
Answer:
x=-15
Step-by-step explanation:
50=-10(x+10)
Distribute 10: 50=-10x-100
Add 100 to both sides: 100+50=-10x-100+100
150=-10x
Simplify: 150/-10=-10x/-10
x=-15
Answer:
849.24 cm²
Step-by-step explanation:
we know it is a cube so to find the surface area of each square you do
12x12=144 and there are 5 sides so 144x5=720
We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle
Now using pythagorus you would do a²+b²=c²
15²+6²=c²
225+36=c²
√261=√c²
16.15=c this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24
now add 720+129.24=849.24 cm²
Answer:
2/6, 5/8, 3/4
Step-by-step explanation:
2/6 = 1/3 = 0.33
5/8 = 0.63
3/4 = 0.75
0.33 < 0.63 < 0.75
