Answer:
Step-by-step explanation:
7*(7 + x+1) = 6*(x + 5 + 6) {Intersecting secant theorem}
7 *(x + 8) = 6*(x + 11)
Distributive property,
7x + 56 = 6x + 66
Subtract 56 from both sides
7x = 6x + 66 - 56
7x = 6x + 10
Subtract 6x from both sides
7x - 6x = 10
x = 10
Their are 26 cats and 19 dogs in the store . 26+19=45 .
The subtraction in the standard form of the polynomial is

Given that
Expression;
.
We have to determine
The subtraction of a polynomial.
According to the question
Expression;
.
To find the subtraction of the polynomial follow all the steps given below.
- Step1; Write the expression as an additive inverse.

- Step2; Rewrite terms that are subtracted as the addition of the opposite.

![\rm 6m^5 + 3 + (-m^3) + (-4m) + m^5 + (2m^3) + 4m + (-6)\\\\(6m^5 + m^5) + [3 + (-6)] + [(-m^3) + (-2m^3)] + [(-4m) + 4m]\\\\](https://tex.z-dn.net/?f=%5Crm%206m%5E5%20%2B%203%20%2B%20%28-m%5E3%29%20%2B%20%28-4m%29%20%2B%20m%5E5%20%2B%20%282m%5E3%29%20%2B%204m%20%2B%20%28-6%29%5C%5C%5C%5C%286m%5E5%20%2B%20m%5E5%29%20%2B%20%5B3%20%2B%20%28-6%29%5D%20%2B%20%5B%28-m%5E3%29%20%2B%20%28-2m%5E3%29%5D%20%2B%20%5B%28-4m%29%20%2B%204m%5D%5C%5C%5C%5C)
- Step4; the resulting polynomial in standard form is,
![\rm (6m^5 + m^5) + [3 + (-6)] + [(-m^3) + (-2m^3)] + [(-4m) + 4m]\\\\ 7m^5-3m^2-3](https://tex.z-dn.net/?f=%5Crm%20%286m%5E5%20%2B%20m%5E5%29%20%2B%20%5B3%20%2B%20%28-6%29%5D%20%2B%20%5B%28-m%5E3%29%20%2B%20%28-2m%5E3%29%5D%20%2B%20%5B%28-4m%29%20%2B%204m%5D%5C%5C%5C%5C%207m%5E5-3m%5E2-3)
Hence, the subtraction in the standard form of the polynomial is

Step-by-step explanation:
By angle sum property
7x-41+5x-12+2x+9 = 180
14x -44 =180
14x =224
x= 224/14
x= 16°
Answer:
-18 =x
Step-by-step explanation:
-7 = -1 + x/3
Add 1 to each side
-7+1 = -1+1 + x/3
-6 = x/3
Multiply each side by 3
-6*3 = x/3*3
-18 =x
