I'm calculated and I figure that it's graphing
Answer:
Solution given:
length[l]=3x+7
breadth [b]=2x+3
we have
area of rectangle=l×b=(3x+7)(2x+3)
=6x²+14x+9x+21=6x²+23x+21 units ²
Answer:
f(x) = (-4/5)*x + 4
Step-by-step explanation:
The line which passes through these points will decrease y by 12 for every x increase of 15. This is the same as decreasing y by 4 for every x increase of 5. This means the slope (rise over run) is -4/5. If this is applied to the first point to find what y is at 0, then the point (0, 4) is on the line.
This means that f(x) = (-4/5)*x + 4
Evaluate the expression and your answer will be 795
Using the Pythagorean Theorem (a^2+b^2=c^2) you can find if the triangle is a right triangle.
