Answer:
3.5
Step-by-step explanation:
(-8)(-1) -2[2-5(-1)]
8 -2 [ 2-5(-1)]
8 -4+10+2
-32+80+16
+32 +32
80=48

3.5
Square-root of two multiplied by the cube-root of 2
=sqrt(2)*(2)^(1/3)
=2^(1/2)*2^(1/3)
=2^(1/2+1/3) multiplication rule of exponents
=2^((3+2)/6)
=2^(5/6)
=(2^5)^(1/6).........sixth root of 2^5
=(32)^(1/6) ............sixth root of 32.
Answer:
The number .
Step-by-step explanation:
Lets assume that the number be .
So accordingly
We have fifteen less than eight times a number that is
And we have,
Eleven more than six times of that number that is
Equating both.
=
Subtracting and adding both sides of the equation.
So finally the number .
Dividing both sides with 13.
Answer:
25 = base
Step-by-step explanation:
I searched all of this on YT to try and help
so first we need to know the area of a Trapezoid
A = 1/2h(b + b)
86 = 1/2(18 + b)4
we dont know the base where going to put b
we also dont like fractions so where going to get rid of 2 by multiplying 2 by 2. And we do it in both ends, so where doing the same with our Area.
172 = (18 + b)4
the 4 is multipling so divide it on both ends.
43 = (18 + b)
then do the opposite operation on the 18, by subtracting 18 on both sides.
25 = b
is the base
check the work by plugging it back in
A = 1/2h(b + b)
A = 1/2 4(18+25)
A = 1/2 4(43)
A = 1/2(172)
A = 86in
