Answer:
80 meters squared
Step-by-step explanation:
The sum of two polynomials is 8d^5 - 3c^3d2 +5c^2d^3 - 4cd^4 +9
2d^5 - c^3d^2 +8cd^4 +1 would be 6d^5 - 2c^3d^2+ 5c^2d^3 - 12cd^4 +8.
<h3>What are polynomials?</h3>
Polynomials are those algebraic expressions that consist of variables, coefficients, and constants. The standard form of polynomials has mathematical operations such as addition, subtraction, and multiplication.
Given that
Now
if one is added i.e.
Now let us assume the other polynomial be x
So,
= x +
x = - ( )
x =

Answer:
m∠2 = 17°
Step-by-step explanation:
y + 10 = 3y - 24
34 = 2y
17 = y
Answer:
n=30
Step-by-step explanation:
1/4(n+2)=8
1/4n+2/4=8
1/4n+2/4-2/4=8-2/4=7 2/4
1/4n=7 2/4
1/4n (4)=7 2/4 x (4)
n=29+2=30
Answer:
Step-by-step explanation:
From the information given,
Mark: 6,7,8,9,10
frequency:5,4,7,10,4
a) Range = highest mark - lowest mark
Range = 10 - 6 = 4
b) The number of students in the group is the sum of the frequency. Therefore,
Number of students = 5 + 4 + 7 + 10 + 4 = 30 students
c) Mean mark = (mark × frequency)/total frequency
[(6 × 5) + (7 × 4) + (8 × 7) + (9 × 10) + 10 × 4)]/ 30
Mean mark = (30 + 28 + 56 + 90 + 40)/30 = 244/30
Mean mark = 8.1
