Answer:

Second option is correct.
Step-by-step explanation:
We have been given the expression 
We can write the term 64 as 
Thus, we have

Now, use the exponent law 

On simplifying, we get

This expression can be further simplified as

Second option is correct.
Answer:
13,600 
Step-by-step explanation:
(h = 7, l = 6, w = 2) 10
70, 60, 20
2(h × w) + 2(h × l) + 2(w × l)
= 2(70 × 20) + 2(70 × 60) + 2(20 × 60)
= 2(1400) + 2(4200) + 2(1200)
= 2800 + 8400 + 2400
= 13,600
Multiply bottom equation by -3 to add and eliminate y’s.
So...
5x-15y=10
+-9x+15y=18
You get -4x=28 so x=-7
Plug in to get y
5(-7)-15y=10
-35-15y=10
-15y=45
So y=-3
Check in other equation
3(-7)-5(-3)=
-21+15=-6
So x= -7 and y= -3
Answer:
<1 = 33
<2 = 90
<3 = 57
Step-by-step explanation:
<3 = 57 because of alternate interior angles
<2 + <3 + 33 = 180
<2 + 57 + 33 = 180
<2 + 90 = 180
<2 = 90
<1 + <2 + 57 = 180
<1 + 90 + 57 = 180
<1 + 147 = 180
<1 = 33
Answer:
2(3) that's multiplication so the answer is A
