Answer: Your answer would be -8
Step-by-step explanation:
You have to divide each side by factors that doesn't contain the variable.

Answer:
r=
r= -
Step-by-step explanation:
8=
Square root both sides of the equation.
r=
r= -
It could be 5x, 5 being the digit, x being "a number"
4x+3y=14
2y=6+4x
we can isolate the y in the second function
2y=6+4x
/2 /2
y=3+2x
then change all the y to 3+2x in first function
4x+3(3+2x)=14
4x+9+6x=14
10x=5
/10 /10
x=0.5 or 1/2
then fill the x in the function, get y.(each function will work)
2y=6+4x
2y=6+4(1/2)
2y=6+2
2y=8
y=4
x=0.5 y=4
Answer:b
Step-by-step explanation:
Height=h
Base=b
area of =1440
area of =(b x h)/2
1440=(bxh)/2
1440x2=bxh
2880=bxh
b=5xh
Substitute b=5xh in 2880=bxh
2880=5xhxh
2880=5h^2
Divide both sides by 5
2880/5=5h^2/5
576=h^2
h^2=576
Take the square root of both sides
h=√(576)
h=24
