Answer:
x^2+10x+16
Step-by-step explanation:
Plug in the values
h=x+8
b=2x+4
A=1/2(2x+4)(x+8)
A=(x+2)(x+8)
FOIL: x^2+8x+2x+16
A=x^2+10x+16
The answer is x=-6.33333 (-19/3)
First, add like terms (12+7), which would equal to 19.
Then isolate the variable by subtracting 19 and adding it to the other side of the equal sign.
Now with this new equation of 3x=-19, isolate again by dividing 3 from x and do the same thing to the other side (-19/3).
The answer should be -6.33 repeating, but in algebra you would give a more simplified answer. This would be -19/3
The length of the other side of the yard is 16 feet
work: 160 divided by 10
hope it helps
The answer would be 10.19m. If you want to round it of to a less precise
measurement it would be 10 m.
√324 * √75 = √24300 = 90√3
so
90√3 / 9 = 10√3
answer is
D. last one 10√3 irrational
