Answer:
Step-by-step explanation:
Let's calculate the answer to the second parenthesis. Just multiply throughout to get -8xyz. Then, multiply the first parenthesis by the second. Multiply the constants (-8 and 2) first to get -16, multiply the x's together to get x^2, the y's together to get y^2, and the z's together to get z^2. Put it all together to get .

Step-by-step explanation:
45 - 45 - 90 Triangles
When one leg = x, the hypotenuse = x
So, if the hypotenuse is 1, then divide by to get the leg.

The middle two. An arithmetic series is when something is added over and over again. Geometric is the same except multiplication. For the first one, it only adds 3. For thr last one, it multiplies by -3. For the middle two, I can't seem to find a pattern.
<span>42:6=7, the dividend is 42, the quotient is 7
so 42= 6x7
8:1=8, 8=8x1
12= 1x12
generalization
let be a:b=q, so a = bx q, a dividend, q quotient and b the divisor</span>
Answer:
Step-by-step explanation:
Line 1
y= 3/2x +7/2 m = 3/2
Line 2
4x-6y+2 = 0 m = 2/3
Line 3
y = 3/2x - 4 m = 3/2
Line 1 and Line 2 = neither
Line 1 and Line 3 = parallel
Line 2 and Line 3 = neither
