'x' was calculated correct.
y = 180° - 78° = <u>102</u><u>°</u>
= -9(x – 4) – 6x
Multiply -9 by everything in parentheses first
= (-9*x) + (-9*-4) - 6x
= -9x + (36) - 6x
Combine like terms
= (-9x-6x) + 36
= -15x + 36
The middle choice is the answer:
-15x + 36
Hope this helps! :)
Answer:
Area of smaller shape = 245 cm²
Step-by-step explanation:
Given:
Scale factor ration [Big shape to small shape] = 14:7
Area of bigger shape = 490 cm²
Find:
Area of smaller shape
Computation:
Area of smaller shape = Area of bigger shape[7 / 14]
Area of smaller shape = 490[7 / 14]
Area of smaller shape = 490[7 / 14]
Area of smaller shape = 35[7]
Area of smaller shape = 245 cm²
