I'm learning the exact same thing so give me some question and I can see what I can do!
Answer
No
Step-by-step explanation:
Since you 4x3=12 3x3 = 9
Answer:
= 8sqrt2
Step-by-step explanation:
Area of a trapezium is given by the formula;
1/2(a+b)h
;
Where a and b are the parallel sides and h is the perpendicular height.
a = 3 cm, b= 5 cm
To get; h, we use the Pythagoras theorem;
h² = 3² - 1²
h² = 8
h = √8
= √4√2
= 2√2
Thus;
Area = 1/2(3 +5) 2√2
= 1/2 ×8 × 2√2
<u> = 8√2 cm² or 8sqrt2 cm²</u>
The answer is 13.
STEPS:
√ (3 - 8)^2 + (8 - (-4) )^2
√ (-5)^2 + (12)^2
√ 25 + 144
√ 139
13
Find the difference between the X and Y values goven:
10 - 1 = 9
12 - 3 = 9
15 - 6 = 9
The difference is 9, so the rule is subtracting 9 from the x value:
y = x -9
Now find Y when x is 20:
y = 20-9
y = 11
