Answer:
Option D. 50 ft
Step-by-step explanation:
we know that
The area of the figure is equal to the area of three rectangles
so


Remember that the area is given

so

solve for x

Answer: 17160 feet
Step-by-step explanation:
We know that 5280 feet = 1 mile
So all we have to do is multiply 3 1/4 by 5280
Let's split the 3 and 1/4 up to make the multiplication easier
3×5280=15840
×5280=
Now add them together
15840+1320=17160
Evaluate the derivative of f(x) at x = 1. I'll use the limit definition:

Then using the point-slope formula, the equation of the tangent line to f(x) at the point (1, 5) is
y - 5 = 9 (x - 1)
y = 9x - 4
Triangle ABC:
m∠A = x° (m∠A is represented by x°)
m∠B = (4x)° (m∠B is 4 times greater than m∠A, you know m∠A is x°, so it is (4x)°)
m∠C = (5x - 30)° (m∠C is 30° less than five times m∠A, so it is (5x - 30)°)
A triangle is 180°, so the angles in the triangle should add up to 180°
The second option is FALSE, so everything else is true
Answer:
twice a number decreased by one
Step-by-step explanation:
Moving from left two right, we see "2 times x, less 1." That's Answer a: twice a number decreased by one. Must do the multiplication before the subtraction.
