Answer:
4(b-6)=b^2
Step-by-step explanation:
The difference would mean that it is subtraction and you multiply that difference by 4 and set it equal to b squared
Answer:
-184
Step-by-step explanation:
The 0.4 isn't 5 or greater so it won't be rounded up as 1.
Answer:
6root2 × 6root2
you have to use pythagoras
a²+b²=c²
c=12
12²=144
a²+b²=144
but it is a square so I'll just change a and b to x because it shows they are equal
x²+x²=144
2x²=144
x²=72
x=6root2
100% - 65% = 35% of students DO NOT participate
980 * 35/100 = 980 * 0.35 = 343 students don't participate
Answer:
480 ft
Step-by-step explanation:
1 ft = 12 in, so 3in : 6ft would be 3in : 72in, which can be simplified to 1in : 24in. then you use the scale to find the lengths. 8in: (24·8)in. 24 · 8 = 192. to convert to feet, do 192/12=16ft. for the width, do the same thing. 15in: (24·15)in. 24·15=360. 360/12=30ft. For area, multiply the length and width. 16·30=480ft.
