Answer: the answer is (2,-4) if that's not the answer then can u post a full picture of the question
Step-by-step explanation:
Answer:
4cm^2
Step-by-step explanation:
First we need to find the length of the height of the triangle using Pythagoras:
a^2+b^2=c^2 (Substitute in what we have)
a^2+3√2(^2)=2√5(^2) = a^2 + 18 = 20 -> 20-18=2 √2=BD
Now we can find the area:
AD+DC= 3√2 + √2 = 4√2 x √2 = 8/2 = 4
Answer:
B
Step-by-step explanation:
3 x -3 is -9
-2 x 4 is -8
-9 x -8 is 72
A 42 24÷16 =1.5 1.5×28 =42 b i think its 78.4 im not sure
Answer:
4
Step-by-step explanation:
- To be perpendicular, the product of the slope is -1.
- (x,y) Substituting the coordinates.
- y= 1/3(x+3) + 1
- y= 1/3x +2
