6 * ( 12 - 7.5 ) - 7
Paladinen [302]

Answer: 20

Explanation: Alright, so basically you’re going to want to use PEMDAS (Parenthesis, Exponents, Multiplication/ Division, Addition/ Subtraction)

* just means multiply.. sooo the problem looks like this:

6x(12-7.5)-7

We’ll start at the parentheses :)

So (12-7.5) = 4.5

Now our problem looks like: 6x(4.5)-7

Following PEMDAS, the next thing to come up is multiplication! So we’re going to multiply 6 by 4.5 ...

6x4.5=27

After this our problem looks like: 27-7

So now it’s just simple math...

27-7= 20

yulyashka [42]

Answer:

-12m + 12m =0

Step-by-step explanation:

Given

Initial\ Position = -12m

Rise = 12m

Required

Represent as an equation

The new position of the hook is calculated by:

New\ Position = Initial\ Position + Rise

This gives:

New\ Position = -12m + 12m

New\ Position = 0

Hence, the equation is:

-12m + 12m =0

The factors of the given expression are x , x - 2 and x - 4

V(x)= x^{3}-  6x^{2}+8x \\  \\ &#10;V(x)=x( x^{2} -6x+8) \\  \\ &#10;V(x)=x( x^{2} -2x-4x+8) \\  \\ &#10;V(x)=x[x(x-2)-4(x-2)] \\  \\ &#10;V(x)=x(x-2)(x-4)

So the expression for height and length are x and x - 4

Nonamiya [84]
Assuming you meant 2+3(67x34)=y
67x34=2278
2+3(2278)=y
5(2278) or 5x2278=y
y=11390
