Ok, so first you solve whatever is in the parentheses.
(28 • 5-5 • 190)-2•228
28• 5 = 140
Then 5 •190 = 950
Then multiply 950 • 140 = 133,000
Then it should look like this:
133,000-2•228
Multiply 2 • 228 = 456
Then subtract 456 from 133,000.
The answer should come out to 132,544.
Answer:
D) -30x^2 -64x -18
Step-by-step explanation:
Given:
f(x) = 6x +2 and g(x) = -5x - 9
f(x).g(x) = (6x + 2) (-5x - 9)
Use distributive property
= 6x(-5x -9) + 2(-5x - 9)
= -30x^2 - 54x - 10x -18
= -30x^2 -64x - 18
Answer: d) -30x^2 -64x -18
Thank you.
<h3><u>Solution:- </u></h3>
Let the number to be added be A
Now,
Transposing (−5x³+ 4x − 3 ) to other side-
Remember if there is a -ve sign before a bracket the signs of whole of the terms changes on opening bracket
Putting like terms together -
Therefore, 5x³+x²-5x +2 should be added to −5x³+ 4x − 3 to get x²− x − 1
4(p - 7) = 44
First distribute the 4 over the parentheses
4p - 28 = 44
Add 28 to both sides:-
4p = 44 + 28
4p = 72
Divide both sides by 4:-
p = 72/4
p = 18 (answer)
