1) Formula: area = height * base / 2
2) Call x the height:
height = x
base = 2x
3) State the equation:
(x)(2x) = 49 in^2
4) Solve the equation:
2x^2 = 49 in^s
x^2 = (49/2) in^2
x = √(49/2) in
x = 7√2 / 2 in = 3.5 √2 in
5) Solution:
height = 3.5 √2 in and base = 7√2 in
6) Verification: area = (7√2 in) (3.5√2 in) = 49 in^2
Answer: height = 3.5√2 in and base = 7√2 in.

Answer:
32x-8y-3
Step-by-step explanation:
4(8x-2y)-3
4 x 8x = 32x
4 x 2y = -8y
I only know 9) and 10) sorry but here they are:
9) x=16 because ...
3x+20=5x-12
(-3x) (-3x)
20=2x-12
(+12) (+12)
32 = 2x
(32/2) (2x/2)
16=x
10) x=46
angles in quadrilaterals add to 360’
So you do ...
360-134-134-46= 46
This is all I know sorry. Hope you find some more help :)
