Answer:
90 in²
Step-by-step explanation:
The figure's area is that of four right triangles, each with legs of 6 in and 7.5 in. The area of each triangle is half the product of the leg lengths, so is ...
triangle area = (1/2)(6 in)(7.5 in)
Then the area of 4 of those triangles is ...
figure area = 4 · triangle area = 2(6 in)(7.5 in) = 90 in²
X = k x y
21 = k x 3
k = 7
x = 7y
x = 7(10)
x = 70
Answer:
the first one is D, the second one is B i think :)
Step-by-step explanation:
Answer:
i have made it in above picture
The answer (I believe) Is 6.
bc you do this...
x+(5x-6)+(5x-6)=54
then solve
