Answer:
see below
Step-by-step explanation:
a)5a−6b+7c from 13a−4b+8c
13a−4b+8c -(5a−6b+7c)
Distribute the minus sign
13a−4b+8c -5a+6b-7c
Combine like terms
8a +2b +c
b)2x²−3xy+4y² from 3x²−5xy−6y²
3x²−5xy−6y² - (2x²−3xy+4y²)
Distribute the minus sign
3x²−5xy−6y² - 2x²+3xy-4y²
Combine like terms
x²−2xy−10y²
c)x²+4xy−3y² from 2x²−5xy+y²
2x²−5xy+y² - (x²+4xy−3y²)
Distribute the minus sign
2x²−5xy+y² - x²-4xy+3y²
Combine like terms
x²−9xy+4y²
d)4x³−6x²+8x−9 from 7x³−16x+18
7x³−16x+18 - (4x³−6x²+8x−9)
Distribute the minus sign
7x³−16x+18 - 4x³+6x²-8x+9
Combine like terms
3x³+6x²−24x+27
No, it is not 1/2.
3/10-2/5 = 3/10-(2*2)/(5*2)
= 3/10-4/10
= -1/10
Answer:
228 inches
Step-by-step explanation:
The scale is 12 inches : 5 yards, that means
Real Life 5 yards is 12 inches in drawing.
This is a ratio
We can write:
Now we can create another ratio where drawing length is "x" and real length is 95 yards.
<u>Note:</u> remember to keep yards on numerator and inches on bottom
So, we can write:
We can equate these 2 ratios and cross multiply and solve for x:
Hence 95 yards would be equal to 228 inches in the drawing
Answer:
B
Step-by-step explanation:
The answer is B, -12.
Please give me brainliest.
-12^2 --> -144
-144+144 = 0
Therefore, the answer is B, -12.
Integers are numbers and absolute value is the magnitude of the numbe non dependent of its sign (absolute value is the number as a positive) ex; the absolute value of -3 is 3... and if the original number is positive it stays the same so ex; the abosolute value of 8 is 8
