Answer: The answer be 87 for both answer's
Step-by-step explanation:
because, {B-3=90} and, 0.< a < 90. and I calculated and got 87 for both questions ( I hope it correct!)
We can check the end terms first
for
(a+b)(c+d), the first term of the expanded is ac and the last term is bd
so
the expanded is x^3 and last is +7
jane will have a lst term of -7 so no
mariah wil have last term of -7 as well, so no
only rojer and nethan have last tem of +7
so we can do the rest of it by doing the OL part of FOIL
do either roger or nethan
let's do nethan
F=x^3
O=-7x
I=-x^2
L=7
yep
it is nethan
Google it and see what you get
Answer:
130356 grams.
Step-by-step explanation:
The table shown in the picture is a proportion table. What I did here was divide 34932 by 4.1. That gave me 8520. So, 1 cm³ of metal is 8520 grams. Now multiply that by 15.3.
8520/1 * 153/10
<em>Cross-cancellation (8520 becomes 852, 10 becomes 1 (GCF: 10))</em>
852 * 153
<em>Multiply 852 by 153 to get 130356.</em>
130356
15.3 cm³ of metal weighs 130,356 grams.
<em>(Long multiplication work is below.</em>
Answer: Choice D) 1
=====================
Use the slope formula
m = (y2-y1)/(x2-x1)
m = (2-9)/(-4-3)
m = (-7)/(-7)
m = 1
----------
Extra Info:
slope = rise/run
slope = 1/1 so rise = 1 and run = 1.
This means each time you go up 1, you move to the right 1.
