Answer:
x = 28
Step-by-step explanation:
The sum of the angles in a straight angle = 180°
Sum the angles and equate to 180
2x + 20 + 3x + 20 = 180
5x + 40 = 180 ( subtract 40 from both sides )
5x = 140 ( divide both sides by 5 )
x = 28
Answer:
There are no solutions.
Step-by-step explanation:
If there is 74 and 54 but with the same 15x: there is no solution. Even with negative.
Answer:
(x + 2)^2 - 11.
Step-by-step explanation:
f(x) = x^2 + 4x - 7
Now x^2 + 4x = (x + 2)^2 - 4 so we have:
f(x) = (x + 2)^2 - 4 - 7
f(x) = (x + 2)^2 - 11.
Answer:
base times height divided by 2 i think i remember
Step-by-step explanation:
Because it's a triangular prism and the base times height makes a rectangular prism, a triangle is half of a rectangle
<span>To answer this question we need to know that because x will always be negative, it is the same as saying lim as x approaches infinity of 1/(1.001)^x. That is why we can say that the denominator will get bigger and bigger, making the fraction and therefore the limit closer and closer to 0. </span>
