Answer:
hi
Step-by-step explanation:
15f -8f+ 13= 55
⇒ 7f+ 13= 55
⇒ 7f= 55- 13
⇒ 7f= 42
⇒ f= 42/7
⇒ f=6
Final answer: f=6~
<u>Answer:</u>

![x + 7](https://tex.z-dn.net/?f=x%20%2B%207)
) </h3>
<u>Step-by-step explanation:</u>
To find the area of a rectangle, we have to multiply the length with the width.
In the question, the given length is 'x' and the width given is 'x +7'
So, the area would be
(
) x (
)
The area = ![x^{2} + 7x](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B%207x)
So, the equation to find the area of such a rectangle would be:-

Answer:
m∠T = 68°
m∠U = 95°
m∠V = 112°
m∠W = 85°
Step-by-step explanation:
m<V = (14z - 7)°
m<W = 10z°
m<T = 8z°
Recall that the sum of the opposite angles of a cyclic quadrilateral equals 180°.
Therefore:
(14z - 7)° + 8z° = 180°
Find z
14z - 7 + 8z = 180
22z - 7 = 180
22z = 180 + 7
22z = 187
22z/22 = 187/22
z = 8.5
A = 21
b = 3
c = 1.3? not sure
d = 8
