because A & B are parallel
3=7 and 1=8 are true
the first 2 are the only ones that are true
Answer:
Given the equation: 4(2x-1)+5 = 3+2(x+1) .....[1]
Distributive property states that when a number is multiplied by the sum of two numbers, then the first number can be distributed to both of those numbers and multiplied by each of them separately.
i.e,
Applying distributive property, in [1]we get;
Simplify:
.....[2]
Like terms are those terms that have the same variables and powers
Combine like terms on each side in equation [2];
8x +(-4+5) = (3+2) +2x
Simplify:
8x + 1 =5 + 2x
The terms which Carey combine are; -4 +5 and 3 + 2
Area of isosceles triangle is 7.8235
Height = base/2 x tan 41 = 2.61
Base length = 2 x ( side length of triangle) x cos 41
6= 2 x ( side length of triangle, assume it b ) x 0.754
6= 1.509 x b
b = 6/ 1.509
b= 3.975
Area = 1/2 b x h
= 1/2 x b^2 Sin square theta
= 7.8235
Answer:
6w⁴ + 8w²
Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = x⁺ᵇ
+ve * -ve = -ve
-ve * -ve = +ve
+ve * +ve = +ve
To solve this problem, we will follow the following steps:
1- get rid of the brackets using the distributive property
2- combine like terms
This can be shown as follows:
w²(-4w² - 2) + (-5w²)(-2w² - 2)
w²(-4w²) + w²(-2) + (-5w²)(-2w²) + (-5w²)(-2)
-4w⁴ - 2w² + 10w⁴ + 10w²
w⁴(-4+10) + w²(-2+10)
6w⁴ + 8w²
Hope this helps :)
The perimeter is the sum of all the sides so we can add all the sides and set it equal to 35:
![x^2-2x+3x-4+x+2+x+9=x^2+3x+7](https://tex.z-dn.net/?f=x%5E2-2x%2B3x-4%2Bx%2B2%2Bx%2B9%3Dx%5E2%2B3x%2B7)
Now we have a quadratic so we can use the quadratic formula to find x=
![\frac{-3+i \sqrt{19} }{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-3%2Bi%20%5Csqrt%7B19%7D%20%7D%7B2%7D%20)
. Now you can plug that into each x to find each side:-)
