Answer:
A=SqRt(c^2-b^2)
Step-by-step explanation:
a^2 + b^2 = c^2
rearrange to solve for a^2
a^2= c^2-b^2
take the square root of each side
a= square root (c^2-b^2)
Answer:
C 64 students have half the height
Answer:
I will go for a part the rest You can do by yourself
Step-by-step explanation:
Multiply the second equation to get same amount of x in both equations
2x=2-3y/2
multiply both equations by 2 to get rid of the fraction in second equation
4x+14y=34
4x=4-3y
subtract equation(2) from equation(1)
14y=30+3y
11y=30
y=30/11, x=-23/22
Answer:
9x + 8.
Step-by-step explanation:
2(x - 3) + 7(x + 2)
= 2x - 6 + 7x + 14
= 2x + 7x - 6 + 14
= 9x + 8.
Hope this helps!
