I NEED HELP ASAP please help out;

What is the surface area of this triangular prism?

Step-by-step explanation:

14x3x2=84

(12x10x2)/2=12x10=120

120+84=204

SA=724 mm^2

Step-by-step explanation:

14*13==182,*2=364

14*10=140

10*12=120, *1/2=60, *2=120

364+140+120=724

SA=724 mm^2

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
