Answer:
30.6 cm²
Step-by-step explanation:
The area of the parallelogram is simply the sum of the areas of the component three shapes - the square and the two triangles.
Area of square = 4.5 cm × 4.5 cm = 20.25 cm²
Area of two triangles = 2 ×(1/2) × 2.3 cm × 4.5 cm = 10.35 cm²
Area of parallelogram = 20.25 cm² + 10.35 cm² = 30.6 cm²
Answer: b.
Step-by-step explanation:
Based on the information given, you can write the following expression:

Where k is the the constant of variation
If y=4/63 when x=3, then you can substitute these values into the expression and solve for k:

Substitute k into the expression. Then the equation is:

Substitute x=5 into the equation. Then, y is:

Answer:
I think the answer is 11.7 units rounded to nearest tenth
Step-by-step explanation:
d=(2−(−4))2+(−7−3)2−−−−−−−−−−−−−−−−−−−√
d=(6)2+(−10)2−−−−−−−−−−−√
d=36+100−−−−−−−√
d=1–√36
d=11.661904
