Answer: D. Subtracting 9 from each side
Step-by-step explanation:
Always start with numbers without variables first before doing anything with x. And make sure one side must not equal 0 unless you're doing polynomials.
I don't know what question you are but basically to find the the area of something u would either add and then multiply or just multiply . It depends on how your teacher taught you
The height of the heater is about 89.3 in.
You can solve this problem with the Pythagorean Theorem. The base is a square. So half way across the middle will the right under the tip of the pyramid. We can use the measurement with the slant height to write and solve the equation below.
23.8^2 + x^2 = 90.1^2
x will be about 89.3.
Answer:
The smallest angle is 27 degrees.
Step-by-step explanation:
The interior angles of a triangle add up to 180.
(2x + 1) + (3x - 3) + 9x = 180
14x - 2 = 180
14x = 182
x = 13
The three angles are 27, 36, and 117,
