Question

Simplify: (16x5 + 8y2) – 7x5

Answer 1

\[(16x^5 + 8y^2) – 7x^5\]

Answer 2

Easy, just operate on the like terms.

Answer 3

answer plz.!

Answer 4

it's correct

Answer 5

pull off these brackets they are useless
\[(16x^5 + 8y^2) – 7x^5\]\[=16x^5 + 8y^2 – 7x^5\]
then group like terms
\[=(16-7)x^5 + 8y^2\]
simplify the brackets

Answer 6

To add, you only take off these brackets without changing the inner stuff when there is no negative sign outside that.

Answer 7

\( \color{Black}{\Rightarrow -(a + b) = -a - b }\)

Answer 8

how is that relevant parth/

Answer 9

still waiting on the answer thou.????

Answer 10

Well. If she tackles such questions, then she'll be able to perform them.

Answer 11

you cant simplify \((16-7)=\cdots\) by your self @Quanda

Answer 12

A. 24xy – 7x5
B. 9x5 + 8y2
C. 9x + 8y
D. 24x5y2 + 7x5
those are the answer choices now just tell me which one.!

Answer 13

as turns out \(16−7=9\)
so \((16−7)=9\)

so \((16−7)x^5+8y^2\)

\(=⋯x^5+8y^2\)

Answer 14

yes...@UnkleRhaukus is letting u do the last and easiest step. 16-7 equals wat? and then that number in front of x^5 + 8y^2 is the answer.

Answer 15

another question.?
An 8-pound bag of tomatoes costs $5.60. At the same rate, what would be the cost of 11 pounds of tomatoes?

Answer 16

$5.60 for 8-pound bag of tomatoes
$5.60/8=$0.70 or 70 cents for 1-pound bag of tomatoes
since we already know 8 pound bag costs $5.60 we need 3 more pounds (0.7 x 3) = $2.1
total for 11 pound bag of tomatoes is therefore $5.60 + $2.10 = $7.70

Answer 17

Evaluate the expression: [(7 x 6) + 15]2 + 8
