The anwser would be -15
3 x (-5) = -15
a) area of a triangle = (base X height) / 2 = 16X9/2 = 72cm squared
b) area of a parallelogram = (base X height) = 26 X 14 = 364 in squared
c) area of a square = (base X width) = 11 X 11 - 121 yds sqaured
d) are of a trapezoid (the hardest) =
(top bases + bottom base) /2 all times height
(6 + 21) /2 times 8
126/2 times 8
63 times 8 = 504 ' squared
Answer:
You can find 0.5% of a number by multiplying the number by
Step-by-step explanation:
Answer:
223
Step-by-step explanation:
Answer:
PR = 24.5
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, that is
= 
( cross- multiply )
18PR = 28 × 15.75 = 441 ( divide both sides by 18 )
PR = 24. 5
