Answer:27^n+3–6*3^3n+3–n*9^n+2
Step-by-step explanation:
Answer:
P = 9+9+14+14= 46cm
A = Base (14 cm) × Height (7cm)
14×7= 98 cm²
3. P= 1.2 +2.0 +1.6= 4.6m
A = 1/2 B×H
= 1/2 1.6× 1.2
= 0.96 m²

STEPS BELOW </h2>
Step-by-step explanation:
<1 + <4 = 180 (supplementary since you can find corresponding side and straight angle)
<1 = 180-35
=145 degrees
<2 =<4 corresponding angles
<2 = 35 degrees
<3 = 35 degree (corresponding to <2)
