Answer:
Step-by-step explanation:
A quadratic equation is given to us and we need to find the solution of the equation. The given equation is ,
Now for finding the roots of the equation , let's use the quadratic formula , or by factorising out the equation . Here I would be using the factorization method , as ,
<u>Hence</u><u> the</u><u> </u><u>Solution</u><u> </u><u>of</u><u> the</u><u> equation</u><u> is</u><u> </u><u>2</u><u>,</u><u>2</u><u>. </u>
The answer to this question is B
It should be 146 square cm.
First, you would start off by finding the areas of the trapezoid.
Formula- h (base+base 2) 1/2= Area
Formula- (4+14) 10 1/2
Formula- 18 x 10 1/2
Formula- 180 1/2
Area- 90 squared cm
Next, we have to find the area of the triangle. This one is a little more tricky because the height is not given. I believe it goes like this-
Formula- bh 1/2
Formula- 14 x 8 1/2 (The reason I chose 8 is because 10 is the height for the first one so 18-10=8)
Formula- 14x4
Area- 56 square cm
5.
6 / t = 9 / (t+2)
9t = 6t + 12
3t = 12
t = 4 answer
The remaining length:-
6 / 4 = 11 / x
6x = 44 so x = 7.33 answer
6. 8 / w = 6 / (w - 5)
6w = 8w - 40
2w = 40 so w = 20 answer
The side marked w - 5 = 20-5 = 15 answer
8/14 = 20/x giving the top side = 35 answer
No it isn't because 22 divded by2 is 11 not 20
