Answer:
I got -8/9
Step-by-step explanation:
Distribute the magical 1 in front of the parenthesis(-1) to 6x and -15 which become -6x and +15 and your new equation should be 3x + 25=2 - 6x + 15, 3x + 25=17 - 6x. Solve from their. Need more help just ask.
Answer:
27/20
Step-by-step explanation:
The absolute value of any expression is always positive or zero
3/5 + 3/4
Add the fractions
27/20
Solution
27/20
Alternate form
1 7/20, 1.35
M2 -2mn + n2 =
4 - (-16) + 16 =
20 + 16 = 36
Have a nice days.......
What we know:
shape is circular
Area=64π yr²
Area=πr²
circumference=2πr
In order to find circumference we need r=radius. We can use the area to find r by solving for r using substitution of the information we know above.
Area=πr²
64π=πr² substitution
64π/π=π/πr² multiplicative inverse
64=r²
√64=√r² properties of radicals
8=r We would get two solutions, a positive and negative one but we will only use the positive solution since radius is positive
Circumference=2πr
C=2π(8)=16π yards
Answer: 7 & 10
