Answer 1

Answer:

Answer:

Step-by-step explanation:

(Tangent Length)^2 = y*(y + 11) You are going to have to use the quadratic formula on this.

Tangent Length = 7

7^2 = y * (y + 11)

49 = y^2 + 11y

0 = y^2 + 11y - 49

a = 1

b = 11

c = - 49

When you solve this quadratic equation you get

x1 = 3.40 which is the answer you go with.

x2 = -14.40 which can't be used. A negative length has no meaning.

The perimeter of a rectangle is 34 units. Its width is 6.5 units. What is its length?

Answers

If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5

What is '7b-2b+3-1' ? Need working and it's equations!!

Answers

7b - 2b + 3 - 1 = 0

(7b - 2b) = 5b
3 - 1 = 2

Thus:

5b + 2 = 0
5b = -2
b = -2/5 = -0.4

7b-2b+3-1=0
5b+2=0
5b=-2
b=-2/5

How do you make a mix number an improperfraction example 4 8/11

Answers

Basically what you do is you multiply the denominator (11) by the whole number (4). Then, you add that to the numerator (8).

For this one it would be 11 x 4 = 44
44 + 8 = 52

4 8/11
= 4+ 8/11
= 44/11+ 8/11
= 52/11

The final answer is 52/11~
