Answer:
-1 (color bow red)
Step-by-step explanation:
first plug x=7
-12/2(7) - 2
-12/14-2
-12/12
-1
Each pencil is .1075 cents
A=A1+A2+A3+A4
A1 (the base)=5×15/2=37.5
A2=A3 (the sides)
A2=15×9/2=67.5
A4=17×15/2=127.5
A=37.5+67.5×2+127.5
A=300
Answer:
Step-by-step explanation:
Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.
Answer:-8j^2-16k
Step-by-step explanation:
First step:-2j^2-(-2)k=-2j^2+2k
Second step:
-6(j^2+3k) use the formula a(b+c)=ab + ac
a=-6 b=j^2 c=3k
-6j^2+(-6).3k
-6j^2-6.3k=-6j^2-18k because we multiplied 6x3=18
So we gather the whole equation And simplify
-2j^2+2k-6j^2-18k
-2j^2-6j^2 +2k-18k(add like terms)6+2=8
-8j^2+2k-18K (subtract Like terms 18-2=16)
And the answer will give -8j^2-16k
