<u>Solving question 1 : What is the sum or difference? </u>
Hence, option A is correct i.e. .
<u>Solving question 2 : What is the sum or difference? </u>
Hence, option D is correct i.e. .
<u>Solving question 3 : Write the Polynomial in standard form. </u>
2 - 11x² - 8x + 6x²
We can combine like terms, and rewriting it in decreasing power of x's.
⇒ - 11x² + 6x² - 8x + 2
⇒ (-11 + 6)x² - 8x + 2
⇒ -5x² - 8x + 2
Hence, option A is correct i.e. -5x² - 8x + 2; quadratic trinomial.
<u>Solving question 4 :</u>
White-sided jackrabbits: 5.5x² - 9.2x + 6.9
Black-tailed jackrabbits: 5.5x² + 9.9x + 1.3
Total population = White-sided jackrabbits + Black-tailed jackrabbits
Total population = (5.5x² - 9.2x + 6.9 ) + (5.5x² + 9.9x + 1.3)
Total population = (5.5 + 5.5)x² + (9.9 - 9.2)x + (6.9 + 1.3 )
Total population = 11x² + 0.7x + 8.2
Hence, option A is correct i.e. 11x² + 0.7x + 8.2
Answer:
m <1 = 61
Step-by-step explanation:
We know that the angle adjacent to 130 is 50 degrees because linear angles are complementary.
Extending line t to make a triangle, we can find the angle adjacent to the angle labeled 111 ( and above it) is 69.
That makes the angle that touches line q 61 to finish the triangle
This angle and angle 1 are corresponding angles, so they are equal
<1 = 61
Answer:
Answer 2) When dividing by -5, he did not change the to
.
Step-by-step explanation:
If you divide or multiply a negative, you ALWAYS change the sign to its opposite.
Hope this helps! :)
The cost price of each pair of socks is 3 dollars and 97 cents
The total money paid by Jessica for 4 pair of socks = $20
The money that the cashier returned = $4.12
It is also given that, each pair of sock would cost same price
We need to find, The cost price of each pair of socks
To do that, first let's find
The amount that was paid for 4 pair of socks = 20 - 4.12 = $15.88
Now,
The cost price of one pair of sock =
= $3.97
= 3 dollars and 97 cents
