Answer:
the first answer is a⁴ +am²
Step-by-step explanation:
when dividing exponents add or subtract each other
a² + a² = a⁴

an and mn cancel each other out
Multiply the numbers on the major axis which are 2 and -9 to get -18. Subtract from that 3*4 = 12. So -18-12 = -30. That's the determinant.
Hello! The formula for finding simple interest is prt. That means multiply the principal (initial amount) by the rate (percentage) by time (months or years). The principal is $893.78 and the interest rate is 2.2%. 893.78 * 2.2% (0.022) is 19.66316. Do not delete that number. The time is 7 years. Now multiply that number by 7 in order to get 137.64212 or $137.64 when rounded to the nearest whole hundredth. Now, let's add both numbers. 893.78 + 137.64 is 1,031.42. There. Alfred's balance after seven years is $1,031.42.
It wouldn’t be any of these I don’t think, however I don’t know what the # means.
I thought it would be C = 15 + x(0.20)
Hope this helps
