Answer:
|x-99|<3
Step-by-step explanation:
|x-99|<3
The answer is 3x^2 + 19x - 12.
Answer:
45
Step-by-step explanation:
Triangles equal up to 180 degrees therefore you do the following to solve this equation. So you have 80 and 55. So you add 80 to 55 and you get 135. Now you subtract 180 by 135 and that equals 45. So x=45. I will write it out as well.
55+80=135
180-135=45
x=45
To check.
80+55+45=180
The value of y that ensures the pool is a rectangle is 3. Option D
<h3>How to determine the value</h3>
The formula for perimeter of a rectangle is expressed as;
Perimeter = 2 ( length + width)
It is important to note that parallel sides of a rectangle are congruent, that is, they are equal.
Given the sides as;
5y + 6 = 8y -3
collect like terms
5y - 8y = -3 - 6
-3y = -9
Make 'y' the subject
y = 3
Thus, the value of y that ensures the pool is a rectangle is 3. Option D

Answer:
1
Step-by-step explanation:
Given:
<u>Substitute the values into the expression:</u>
1/2(m - 4) × n
⇒ 1/2(12 - 4) × 1/4
<u>Simplify the expression:</u>
⇒ 1/2(8) × 1/4
⇒ 4 × 1/4
⇒ 4 ÷ 4
⇒ 1 (Option B)
