Answer:
7.25 × 10^6
Step-by-step explanation:
1) put into standard form: 6,000,000 + 1,250,000
2) add: 6,000,000 + 1,250,000= 7,250,000
3) put into scientific notation: 7.25 × 10^6
Answer: easy. The value is 3 tenths.
Step-by-step explanation:
Answer:
18.
Step-by-step explanation:
1) formula of the perimeter given in the condition is:
p=2(VW+XV) or p=2(VY+XY).
Note, VW=XY and XV=VY;
2) if to substitute p=84, VW=2z+2 and XV=3z into the formula above, then
2(2z+2+3z)=84, ⇔ 5z+2=42; ⇒ z=8.
3) if z=8, then VW=2z+2=2*8+2=18.
Answer:
8−4 a
Step-by-step explanation:
x=g(h(a−4))
h(a−4)=−2(a−4)−5 = −2 a+8−5=3−2 a
Apply g.
g(h(a−4))=g(3−2a)=2(3-2a)+2=6−4a+2
