Answer:
12.8 IN.
Step-by-step explanation:
So, what exactly is perimeter?
Perimeter= 2L+ 2W
In this question we were given the length.ie.Base and the perimeter itself.
●Length is 39 In.
●Perimeter is 103.6 In.
●We don't know the width.
But, as per given the question, we know that;
1 length = 39 In.
2 lengths= 78 In.
Now that we know the <u>total</u><u> </u><u>length</u><u> </u><u>we</u><u> </u><u>can</u><u> </u><u>find</u><u> </u><u>the</u><u> </u><u>total</u><u> </u><u>width</u><u>.</u>
See as follows,
103.6 - 78= 25.6
<u>2</u><u> </u><u>widths</u><u>=</u><u> </u><u>25</u><u>.</u><u>6</u>
<u>1</u><u> </u><u>width</u><u>=</u><u> </u><u>25</u><u>.</u><u>6</u><u>÷</u><u>2</u>
<u>=</u><u>12</u><u>.</u><u>8</u><u> </u><u>In</u>
It's c bro it's 100% C trust me (c)
Answer:
x=0.450765 or x=−0.950765
Step-by-step explanation:
14x² + 7x - 6
→ Find the product, sum and factors
Product = -6
Sum = 7
Factors = No factors
→ Since there are no factors utilise the quadratic formula
→ List the values of a, b and c
a = 14
b = 7
c= -6
→ Substitute into the formula
→ Simplify
x=0.450765 or x=−0.950765

6. D
Step-by-step explanation:
4. The radius is 3 units (3 boxes). So you do pi*r^2 = 3.14*9
5. You want the area of the box minus the area of the two circles.
Height of the box is 8 (bottom of circle to the top is two times the radius). Width of the box is 16 (left end of the left circle to the right end of the right circle) so 4 times the radius of the circles. Area of box is 128
Area of each circle is 3.14*(16). So you do 128 - 2*3.14*16.
6. Just plug in the radius 9 to the area of a circle formula: pi*radius^2 = 81*pi
