Answer:
(7/8 - 4/5)^2 = 9/
1600
= 0.005625
Step-by-step explanation:
Subtract: 7/
8
- 4/
5
= 7 · 5/
8 · 5
- 4 · 8/
5 · 8
= 35/
40
- 32/
40
= 35 - 32/
40
= 3/
40
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - seven eighths minus four-fifths = three fortieths.
Exponentiation: the result of step No. 1 ^ 2 = 3/
40
^ 2 = 32/
402
= 9/
1600
In words - three-fortieths squared = nine one-thousand six-hundredths.
Answer:
c. (1,-2)
Step-by-step explanation:
by adding them together you can cancel out the y's and solve for x. once you get x, you can plug it into either equation and get y.

Answer:
D) -12
Step-by-step explanation:
Y= mx + b
m(slope) = 1/2
b(y-intercept) = 6
y= 1/2x + 6

Answer:6,200,000,000
Step-by-step explanation: Since the exponent get smaller the number get bigger therefore don't get confused on whether it is a decimal because all whole numbers have a imaginary decimal.
The perimeter is all the sides added up.
s1+s2+s3+s4= p
So, 12+ 6+ 8+ 17= the perimeter.
12+6+8+17 = 43
The answer is 43.
I hope this helps!
