(12 + x) X 4.
EXPLANATION
Replace twelve with 12.
Replace the sum with a +
Replace a number with a variable
replace four times with X 4.
Have a gud day
Let the first number be A. and the second number B.
A + B=12-------equation1 and
A ×B =-64------eqn2
from eqn1,
A =12 - B
so put A=12-B into eqn 2
(12-B) ×B=-64
.12B-B^2=-64
B^2-12B-64=0
now use calculator to find the answer.
u will get two answers, but u haven't finished yet. if B is = X,
put Xinto A=12-B
to find the value of A.
and so the same for the second number.
You will need the formula of a rectangular prism and fill the missing info!
Answer:
very easy
Step-by-step explanation:
First of all
made a distance between
AB
BC
CD
AD
and diagnals
AC
BD
If the all are equal means it is a square
if diagnols are different means it is rectangle
if diagnals are not equal means it is parallelogram
thats it try your best
you can do it
best of luck
Answer:
C
Step-by-step explanation:

Like
X =5y - 11
Then you will get
X+11=5y
Then x+11/5=y
