Answer:
The solutions to the equation are 1, 0.375.
Step-by-step explanation:
The equation is already in factored form.
The solutions to the system are the values of x that make one or the other of the factors be zero.
x -1 = 0 . . . when x = 1
8x -3 = 0 . . . when x = 3/8 = 0.375
There is only one variable, so no "ordered pairs" are involved.
The solutions are {1, 0.375}.
First, the bigger square's area is 20*20= 400 cm^2
second, the circle's area is ¶r^2 = ¶(20/2)^2 = ¶(10)^2 = 100¶ cm^2
third, smaller square-- if we imagine it as 4 parts as 4 right triangles-- 1 part will be 1/2*(20/2)(20/2) = 1/2 (10)(10) = 50 cm^2 then the area of the smaller square is 4*50 = 200 cm^2
so the shaded parts = circle - smaller square =100¶ - 200 cm^2
the answer is 2
Answer:
-15c + 2
Step-by-step explanation:
you start by multiplying the coefficients of the parentheses to the numbers inside which gives you
- c - 32c + 5 + 18c - 3
then you simply just group together the like numbers. all "c" 's go together and everything without a "c" goes together
- 1c - 32c + 18c= -15c
5 - 3 = 2
the final answer simplified is
-15c + 2
Answer:
Round 34 down to 30 then round 39 up to 40
Step-by-step explanation:
34 ⟶ 30 34 is rounded down to 30
39 ⟶ 40 39 rounded up to 40
34 ⟶ 30
39 ⟶ 40
34 is rounded down to 30
39 rounded up to 40
Calculate mentally 34 × 39 = 1326
The estimated product is 1326.
