Answer:
A) -8x^2 - 26x - 15
Step-by-step explanation:
(4x + 3)(-2x - 5)
FOIL
first: 4x*-2x = -8x^2
outer : -5*4x = -20x
inner: -2x*3 = -6x
last: -5*3 = -15
Add these together
-8x^2 -20x-6x -15
-8x^2 -26x-15
This would be 1 1/2 using a calculator

When you multiply it out by hand to get
2678 × 97 = 259766
you place the decimal point in the answer by counting the number of decimal places of the multiplicands.
2.678 has 3 decimal places
9.7 has 1 decimal place
The product of these numbers will have 3+1 = 4 decimal places, so will look like
B) 25.9766
___
You can also get there by considering that the product is about 10×2.6, so is about 26. That will tell you the decimal point goes after the first two left-most digits.
Answer:
x = 67°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for x , that is
x = 180° - (38 + 75)° = 180° - 113° = 67°
