Answer:
2×2×2×2+7×7−5×5×5 =2⁴ + 7² - 5³
Step-by-step explanation:
Answer:
y = 4
Step-by-step explanation:
5/2y = 10
5/2y x 2/5 = 10 x 2/5
Multiply each side by the reciprocal
y = 4
Perpendicular has slope that mutiplies to -1 to the other slope
for
ax+by=c
slope=-a/b
-1x+3y=9
-(-1)/3=1/3
1/3 times what=-1?
-3
y=mx+b
m=slope
y=-3x+b
find b
(-3,2)
(x,y)
x=-3
y=2
2=-3(-3)+b
2=9+b
mnus 9
-7=b
equaton is
y=-3x-7 or
3x+y=-7
Answer:
Part 5) Option b
Part 6) Option d.
Step-by-step explanation:
Part 5) we know that
The area of a square is equal to
where
b is the length side of the square
we have
substitute
Solve for b
take square root both sides
Remember that
substitute
Applying property of exponents
Part 6) we know that
The volume of a cube is equal to
where
b is the length side of the cube
we have
substitute
Solve for b
take cubic root both sides
Remember that
substitute
Applying property of exponents
