Answer:
Step-by-step explanation:
x + 4 + 6x - 47 = 90
7x - 43 = 90
7x = 133
x = 19
S = 19 + 4 = 23
R = 6(19) - 47 = 114 - 47 = 67
length is 4
area= l*w
4-3=1
4*1= 4
Answer:
4 times 10 to the negative seventh power
Step-by-step explanation:
We can see that the decimal has 6 zeros before it, and then it’s 4.
since there are 7 digits after the decimal point, we put 10 to the negative seventh power.
that gives us 0.0000001
to get 0.0000004, we need to multiply ten to the negative seventh power (0.0000001) by 4
The answer is a. which is 4 x 10‐⁷
