Answer:
Step-by-step explanation:
-4 - 7 + 10x = -7 + 6x...combine like terms
10x - 11 = 6x - 7
10x - 6x = -7 + 11
4x = 4
x = 4/4
x = 1.........ONE SOLUTION
<h3>Answer:</h3>
w+x+y+z = 12
<h3>Explanation:</h3>
When right angle ADC is divided into three equal parts (trisected), each of those parts is 90°/3 = 30°. Thus, ∠CDB = ∠PBD = ∠PDB = 30°.
The sides of a 30°-60°-90° triangle are in the proportion 1 : √3 : 2. Hence BD = 2, and PD = PB = 2/√3 = (2/3)√3.
Then the perimeter of ∆BDP is ...
... perimeter ∆BDP = BD + DP + PB
... = 2 + (2/3)√3 + (2/3)√3
... = 2 + (4√3)/3 . . . . . . . . w=2, x=4, y=3, z=3
w + x + y + z = 2+4+3+3 = 12
Answer: altitude: 5 cm
Explanation:
![\sf \dfrac{1}{2} ( a + b) h = Area \ of \ trapezium](https://tex.z-dn.net/?f=%5Csf%20%5Cdfrac%7B1%7D%7B2%7D%20%20%28%20a%20%2B%20b%29%20h%20%3D%20Area%20%5C%20of%20%5C%20trapezium)
[ <u>a and b are bases, h is the altitude</u> ]
Here given:
Solve for altitude:
![\sf \rightarrow \sf \dfrac{1}{2} ( 6 + 8) h = 35 \ \ \ \Rightarrow \ \ \ \dfrac{1}{2} ( 14) h = 35 \ \ \ \ \Rightarrow \ \ \ \ 7 h = 35 \ \ \ \ \Rightarrow \ \ h = \dfrac{35}{7} \ = \ 5](https://tex.z-dn.net/?f=%5Csf%20%5Crightarrow%20%5Csf%20%5Cdfrac%7B1%7D%7B2%7D%20%20%28%206%20%2B%208%29%20h%20%3D%2035%20%20%5C%20%5C%20%20%5C%20%20%5CRightarrow%20%20%5C%20%5C%20%5C%20%5Cdfrac%7B1%7D%7B2%7D%20%20%28%2014%29%20h%20%3D%2035%20%5C%20%5C%20%5C%20%5C%20%5CRightarrow%20%20%20%5C%20%5C%20%5C%20%20%5C%207%20h%20%3D%2035%20%5C%20%5C%20%5C%20%5C%20%20%5CRightarrow%20%5C%20%5C%20%20%20h%20%3D%20%5Cdfrac%7B35%7D%7B7%7D%20%5C%20%20%20%3D%20%20%5C%20%205)
