Answer:
3x^2-6x -3
Step-by-step explanation:
(2x^2-5x+1)+(x^2-x-4)
we sum all coefficient according to the exponent of the variable
2x^2-5x+1+x^2-x-4 = 3x^2-6x -3
Area of a triangle = base x height / 2
64 = base x height / 2
(multiply 2 on both sides)
128 = base x height
then if base= 16 and height = 8 then 16 x 8 = 128
thus the base is 16 which is twice the height:8
Given:
A race car game takes 6 points from a player each time the player hits a cone.
To find:
The integer which represents the change in total points if the player hits 10 cones.
Solution:
According to the given information,
1 hit = -6 points
Here, negative sign represents the reduction in points after hitting a cone.
If the player hits 10 cones.
(1 × 10) hit = (-6 × 10) points
10 hit = -60 points
So, the change in total points if the player hits 10 cones is -60.
Therefore, the required integer is -60.
1- 3(-2^2t)-7
2- 12+5=17
3- -10-6= -16
4- 2(-5^3)= -250
I can’t find the first one because of t
Answer:
8 years approximately
The problem (I'm assuming is):
Solve 
.
I put a t in the problem where I suspected it in went.
Step-by-step explanation:
Divide both sides by 100:
Rewrite in logarithm form.
Divide both sides by 0.05:
Put left hand side into calculator:
So about 8 years if I wrote down the equation correctly.
