Agreed that this statement is true indeed
Answer:
- 4x² - 8x - 3
Step-by-step explanation:
We want to calculate
1 - (2x + 2)² ← expand using FOIL
= 1 - (4x² + 8x + 4) ← distribute parenthesis by - 1
= 1 - 4x² - 8x - 4 ← collect like terms
= - 4x² - 8x - 3
By definition,
tanC = (opposite side)/(adjacent side)
= 8.77/2
= 4.385
From the calculator, obtain
m∠C = atan(4.385) = 77.1°
Answer: 77° (nearest whole degree)
Answer:
(0,7.5)
Step-by-step explanation:
2x^2 + x -3 can be factorised
<span>[2x + 3][x - 1] </span>
<span>As length times width = area </span>
<span>one possible set of measurements are </span>
<span>length = [2x + 3] </span>
<span>width = [x-1] </span>
