Equation: 4x+15=31
I have included a picture of my work since explaining might be difficult but the way I solved this if the beginning of algebra and I hope it makes sense.
Your welcome, Katy
Answer:
432
Step-by-step explanation:
Volume of cuboid:
12 x 4.5 x 5.5 = 297
volume of traingular prism:
(12x5)/2 x 4.5 =135
add them together:
135+297 =432
hope this helps!
Answer:


Step-by-step explanation:
we are given a vertex of a square i.e <u>(</u><u>1</u><u>,</u><u>1</u><u>)</u>
and the equations of the two parallel sides
notice that, the given vertex coordinates satisfy one of the parallel side i.e <u>y=</u><u>x </u>which means that (1,1) points lie on one of Parallel sides
remember that,
every angles of a square is <u>9</u><u>0</u><u>°</u><u> </u>
therefore,
we need to figure out the remaining <u>Perpendicular</u><u> </u><u>line </u><u> </u>of the given Parallel sides so
let's figure out the perpendicular line of y=x line
recall that,
Parallel lines have the same slope thus

since we are given a vertex the equation of the perpendicular line should be

distribute:

add 1 to both sides:

to figure out the second perpendicular line we can consider the coordinates (0.5,0.5) of y=x equation
so the slope of the perpendicular line is -1
and the equation:

distribute:

add 0.5 to both sides:

and we are done!
Answer:
m<ACB=1/2 of m<AOB
so m<ACB=45⁰÷2
m<ACB=22.5⁰
I HOPE IT HELPS HAVE NICE DAY!
Answer:-8/6=y
Step-by-step explanation:
You have to do KCF which means keep the number on the left or right left in this case, change the mark to a multiplication symbol, and then flip the other fraction which means 3/8 will be 8/3 and if you are looking for a mixed fraction asnwer would be -1 1/3 pls mark as brainliest if right
