Answer:
Step-by-step explanation:
The area is the sum of three sections: rectangle and two same triangles
<u>Rectangle has sides of </u>
<u>Triangles have sides of </u>
The missing number is 5 for both parts of the equation
Correct option is B
5x + 3 ≥ 10
3 is adding on the left, then it will subtract on the right
5x ≥ 10 -3
5x ≥ 7
5 is multiplying on the left, then it will divide on the right
x ≥ 7/5
x ≥ 1.4
Then, the smallest integer value of x is 2
Answer: D) Reflection across the y-axis;
counterclockwise rotation about the origin
so you have your two equations 3x+7=5x-23 and solve for x which is your "number" leaving the answer to be <u>x=15</u>
