8x^3 -5x^2 + 8x + 9+5x^3 + 3x^2 - 5x + 4 =
8x^3+5x^3-5x^2 + 3x^2+ 8x - 5x+ 9<span>+ 4 = </span>
13x^3-2x^2+3x+13
Equation = a² + b² = c²
a = 80
b = 39
c = Diagonal
a² + b² = c²
80² + 39² = c²
6400 + 1521 = c²
c² = 7921
c = √7921
c = 89
Answer = 89 units
x = 10
since GI bisects ∠DGH then ∠DGI = ∠IGH, hence
2x - 13 = x - 3 ( subtract x from both sides )
x - 13 = - 3 ( add 13 to both sides )
x = 10
A can be converted since it is a repeating decimal
Answer:
6
Step-by-step explanation:
Question tests the ability to get quotient
Here, 32 ft is divided by 5’3”
Normally, ft is denoted by ' while inches is denoted by ". So we divide 32 ft by 5ft and 3 inches
First, we convert dimensions into similar units. To convert 5’3” to ft, we divide 3” by 12 hence 3÷12=0.25'
The total is now 5.25'
Now
32'÷5.25'=6.1538461538461
This means, we shall obtain 6 whole pieces with some remainder. Since the question needs the whole pieces only, then the answer is 6
