Answer:
7e+10 + 9e+8 + 6.7e+4 + 8.99 × 10 to the power of 2 + 1/3.
Step-by-step explanation:
Answer:
Length = 30.4 ft
Width = 3.6 ft
Step-by-step explanation:
Width: x
Length: 4x + 16
2(x) + 2 (4x + 16) = 68
2x + 8x + 32= 68
10x = 68 - 32
x = 36/10
x = 3.6
Width = 3.6 ft
Length: 30.4 ft
open the parenthes. and then after that you'll get 27+12x-15. if you simplify that then you'll get 12x+12
Answer:
Step-by-step explanation:
=> 3(5k + 2) + 5 = 3k - 1
=> 15k + 6 + 5 = 3k - 1
=> 15k + 11 - 3k + 1
=> 12k + 12
<u>Hence, correct answer is 12k + 12.</u>
The roots are 1 +√7 and 1 -√7.
<h3>What is Quadratic equation?</h3>
A quadratic equation in the variable x is an equation of the form ax² + bx + c= 0, where a, b, c are real numbers, a≠0
Given equation:
y= x²+2x-6
First,
Half the coefficient of x and add and subtract the square of (b/2)
y= x²+2x-6+(1)²-(1)²
y= x²+2x+(1)² -6 -(1)²
y= (x+1)² -7
Now, equate y=0
(x+1)² -7 =0
(x+1)² = 7
x+1= ±√7
x=1 ±√7
Hence, the roots are 1 +√7 and 1 -√7.
