Answer:
I'll solve 27. To give you a hint.
m2 = 1 + 3x
180 = 1 + 3x
-1 -1
179 = 3x
/3 /3
x = 59.6666667 rounded up
x = 59.67
Answer:
Sum of real parts: 12
Sum of imaginary parts: 3
Step-by-step explanation:
(22 − 5i) + (−10 + 8i)
Combine the real and imaginary parts in numbers 22 − 5i and −10 + 8i
22 − 10 + (−5 + 8)i
Add 22 to −10. Add −5 to 8
12 + 3i
So, the answer is:
Sum of real parts: 12
Sum of imaginary parts: 3i
The real part is 12, the imaginary part is 3
Answer:
1500 cm²
Step-by-step explanation:
→ State area of circle formula
π × r²
→ Substitute in values
22/7 × 70² = 1500
→ Include units
1500 cm²
The total number of DVDs that she bough is 6
<h3>Linear equations</h3>
Linear equation are expression that has a leading degree of 1.
Let the price of each DVD be x such that if Grace bought a television for $329 and some DVDs for $5.75 each and spent a total of $363.50, ten;
329 + 5.75x = 363.5
Subtract 329 from both sides
329 + 5.75x - 329 = 363.5 - 329
5.75x = 34.5
x = 34.5/5.75
x = 6
This shows that the total number of DVDs that she bough is 6

The given expression can be simplified in many ways by grouping like terms. The simplest form is obtained by factoring out a²b which gives us the following expression.
a²b(7 + 10b +14b²)
