Answer:
4x^{3} + 6x^{2} -10x -15
Step-by-step explanation:
(2x+3)(2x^{2} -5)
2x × 2x^{2} + 2x× (-5) + 3× 2x^{2} + 3 ×(-5)
=4x^{3} -10x + 6x^{2} -15
= 4x^{3} + 6x^{2} -10x -15
Answer:
Step-by-step explanation:
a) perimeter = 8x + 3 + 5 + 7x + 4
b) perimeter = 15x + 12
Answer: D. 7^11
Step-by-step explanation:
For exponents with the same base, we just add the exponents and keep the same base. 7 is the same base; therefore 5+6=11 which means the answer is 7^11
The correct equation should look something like this:
y= -1x - 2
Consider the equation for a line:
y = mx + b,
Where ‘m’ is the slope
Where ‘b’ is the y-intercept.
From there you can plug in your known values for ‘m’ and ‘b’, and get the equation above. If you are still not convinced, I suggest you graph the function and observe its slope and y-intercept.
Hope this helps!
Answer:
Figure d)
Monopars are figures that have just one set of parallel lines.
Step-by-step explanation:
It looks like all the figures in group 1 have one set of parallel lines. In group 2, they either have 0 or 2. In group 3, only d has just one set of parallel lines.
So monopars are figures that have just one set of parallel lines.
