Answer:
Step-by-step explanation:
Because of the right angle (90 deg) in red, and the horizontal line on the bottom axis,
we know that :
49 + (1+5x) = 90
solving for x delivers x=8
Answer:
x+2
Step-by-step explanation:
6x2 + 30x+ 36
Factor out the greatest common factor
6 (x^2 +5x+6)
Factor inside the parentheses
That 2 numbers multiply to 6 and add to 5
2*3 = 6
2+3 = 5
6(x+3)(x+2)
Answer:
y = 3/2x - 4
Step-by-step explanation:
Answer:
we know,
area of circle = πr²
area of semicircle of circle having diameter of 16.
according to formula = πr²
radius = 16/2 = 8 cm
22/7 × (8)² → 22/7 × 64 → 1408/7 = 201.14/2 = 100.57 cm (approx.)
area of semicircle of circle having diameter of 20 cm.
22/7 × 20² = 22/7 × 400 = 8800/7 = 1257.14/2 = 628.57
to get the area of shaded part 628.57 - 100.57 = 528 cm² (approx.)
hope this helps you!
