Answer:
what this makes bi sense haha
Step-by-step explanation:
but ok
Answer:
2 triangle surfaces: 2.5 X 2 X 1.7 = 8.5 square meters
9 X 2 = 18 square meters
18 X 3 = 54 square meters
54 + 8.5 = 62.5 square meters
Answer:
B. w = 4
Step-by-step explanation:
As we know, in a parallelogram length of opposite sides are equal.
so, AD = BC
⇒ 4w - 5 = 7w - 17
⇒ 12 = 3w
⇒ w = 4
Answer:
50.274in
Explanation:
Half circle perimeter
9/2 = 4.5
2 * pi * 4.5 = 28.27433388230814
28.27433388230814 + 5 + 12 + 5 = 50.27433388230814
Answer = 50.27433388230814
Rounded to nearest hundredth = 50.274
I hope I helped. Brainliest would be appreciated
We need to solve for x by completing the square of the given mathematical expression (x+7)(x-9) = 25.
First, we need to perform multiplication of (x+7) and (x-9) such as the expression become:
(x+7) (x-9) = 25
x² -9x +7x -63 = 25
x² - 2x = 25 + 63
Then perform addition of constant values 25 and 63
x² - 2x =88
Add +1 in both sides to complete the expression such as:
x² - 2x +1 = 88 +1
(x-1)(x-1) = 89
(x-1)² = 89
We see that (x-1) is a perfect square, we can now solve for the value of x such as:
(x-1) = +-√89
x1 = +√89 + 1
x1 = 10.4
x2 = -√89 +1
x2 = -8.4
The answers are 10.4 and -8.4.
