8 x 6 = 42 add two zeros so 4200
Answer:
y= 128, x=52
Step-by-step explanation:
The Sum of all the angles in a quadrilateral is 360.
y is 128 because both those angles are equal
the other 2 angles are also equal to each other.
360 - 128-128= 104
104/2 is 52
230 is written as 2.3 × 10^2
Answer:
- 8
Step-by-step explanation:
Given
(4 +4 x²)(3x² - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
4(3x² - 5) + 4x²(3x² - 5) ← distribute parenthesis
= 12x² - 20 + 12
- 20x² ← collect like terms
= 12
- 8x² - 20
with coefficient of x² term being - 8
