Make a t diagram between two cars
Answer:
6x^2+2x-6
Step-by-step explanation:
In the expression (2x)(x2)+(2x)(x)+(2x)(-2)+(3)(x2)+(3)(-2) take each set of two and solve those individually. The expression then becomes 4x^2+2x^2-4x+6x-6 the combining like terms you get 6x^2+2x-6.
Answer:
x=145
Step-by-step explanation:
There are two ways to solve:
-Vertical angles Theorem states that opposite angles are congruent, so x=145 degrees.
-Sameside angles are supplementary so:
35+x=180
Subtract 35 from both sides:
x=145
11*11=121
14*14=196
14-11=3
121+196=317
The integers are 11 and 14
X^2 - 4 x = -2
Add 4 to both sides:
x^2 - 4 x + 4 = 2
Write the left-hand side as a square:
(x - 2)^2 = 2
Take the square root of both sides:
x - 2 = sqrt(2) or x - 2 = -sqrt(2)
Add 2 to both sides:
x = 2 + sqrt(2) or x - 2 = -sqrt(2)
Add 2 to both sides:
Answer: x = 2 + sqrt(2) or x = 2 - sqrt(2)
