Answer:
175 m
Step-by-step explanation:
We are given;
- The perimeter of a rectangle as 25 m
We are required to determine the new perimeter if the sides of the rectangle are multiplied by 7.
We know that;
Perimeter of a rectangle = 2(L+W)
Therefore, initially;
2(L+W) = 25 m
Hence;
L + W = 12.5 m
if the sides are multiplied by 7, then;
New length = 7L
New Width = 7W
Thus;
New perimeter = 2(7L+7W)
= 14 (L + W)
but, L + W = 12.5
Thus;
New perimeter = 14 (12.5)
= 175 m
Therefore, the new perimeter will be 175 m
12 + 12 + 7 + 7 = 38 yards
$1.33 x 38 yards = $50.54
Answer = $50.54
Answer:
($/Month * 2) + ($/Month * .5)
($425 * 2 ) + ($425*.5)
($850) + ($212.5) = $1062.50
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
ax^2 + bx + c = 0
a(x^2 + b/a x) + c = 0
Completing the square:
a [ (x + b/2a)^2 - b^2/4a^2] + c = 0
a[ (x + b/2a )]^2 - b^2 / 4a + c = 0
a[ (x + b/2a )]^2 = b^2 / 4a - c
Dividing both sides by a:
(x + b/2a )^2 = b^2/4a^2 - c/a
Taking square roots of both sides:
x + b/2a = +/- √ (b^2/ 4a^2 - c/a)
x + b/2a = +/- √ [ ( b^2 - 4ac) / 4a^2 )]
x + b/2a = +/- √ ( b^2 - 4ac) / 2a
Subtracting b/2a from both sides and converting the right side to one fraction:
x = [- b +/- √ ( b^2 - 4ac] / 2a.
Answer:17% increase
Step-by-step explanation: 350-300= 50
50/300=1/6
1/6=.17
.17=17%
