Mathematics High School

I'm kinda confused can anyone help. I think it's either 32 or 16.

Answers

Answer 1

Answer:

It’s B

Step-by-step explanation:

Because the area is 64 and the base is 4, then you would have to divide 64 by 4 to get 16 which is the height!

Answer 2

Answer:

it would be C. h=32 cm

Step-by-step explanation:

the formula for area of a triangle in A=1/2*b*h

so plug what you know into the formula, you know the area, A, and the base, b, so:

64=1/2*(4)*h

now solve what you can:

64=2h

then divide each side by 2 to get h, or the height, alone:

32=h

so, the height is 32 cm!

im sorry if this didnt make sense, but i hope this helped!! :D

Answer:

448=h

Step-by-step explanation:

512 - h = 16 x 2²

512 -h = 64

then subtract 512 from both sides

-h = -448

two negatives equal a positive

h=448

4/3 = x/21
So you can cross multiply and divide:
3x = 84
x = 28

Or you can say 3 times what equals 21? The answer is 7. Then multiply 4 times 7 to get the answer. Whichever makes more sense to you :)
