10. a. x=12
b. m 10.
a. x=12
b. m11.
a. Y=55 W=75 Z=45
b. Chelsea’s solution was incorrect because if you add all the angles up you only get 175 and a triangle measures 180 degrees. .
Let's solve your equation step-by-step.
−3(x+4)=−24
Answer:
x=4
<em>A(a) = 24 cm²</em>
<em>A(b) = 40.04 cm² ≈ 40 cm²</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>area formula (rectangle)</em>
<em>A = l × w</em>
<em>A(a) = 8cm × 3cm = 24 cm</em>
<em>A(b) = 5.2cm × 7.7cm = 40.04 cm² ≈ 40 cm²</em>
<em>Good luck !</em>
