Answer:
14.8
Step-by-step explanation:
By the Pythagorean theorem, ...
... x² = 7² + 13² = 218
... x = √218 ≈ 14.7648 ≈ 14.8
Answer:
d) intersecting, but not perpendicular lines
Step-by-step explanation:
Changing the sign of one of the variable terms causes the line to be reflected across one of the axes. The slope is the opposite of what it was. Since the original slope was not 1 or -1, the resulting line is not perpendicular to it. Lines with different slopes will be intersecting.
The two lines are intersecting, but not perpendicular.
Answer:
D
Step-by-step explanation:
SA = bh + (s1 + s2 + s3)H is the formula to find out the surface area
b is base, h is height (small height), s's are the sides, H is the height (longer one)
SA = 12(9) + (10 + 10 + 12)32
SA = 108 + (32)32
SA = 108 + 1024
SA = 1132
Answer:
answer would be the first choice.
Step-by-step explanation:
you would need to factor out x from the expression, then factor out -3 from the expression, factor the expression using a^2-B^2=(a-b)(a+b), afterwards you factor out the 4 from the expression, and then the 3x. Next you would factor out 2x+1, reduce the expression with x-5, reduce the numbers with the greatest common divisor 2, you then reduce the expression with x-3, multiply the fractions, distribute 2 through the parenthesis, distribute the 3x through the parenthesis, and that should be all.
.5 -(-7) would be just 7 because of the imaginary -1 it’s being multiplied 7+1+3-7=11 then divide
