I dont think so because an acute angle is always lower than 90 so .. i dnt think even two will add up more than 90

Evaluate the function when x = -1, 5, -10 *

postnew [5]

Step-by-step explanation:

f(x) = | x² - x + 3 |

f(-1) = |(-1)² - (-1) + 3| = |1 + 1 + 3| = |5| = 5

f(5) = |(5)² - (5) + 3| = |25 - 5 + 3| = |23| = 23

f(-10) = |(-10)² - (10) + 3| = |100 - 10 + 3| = |93| = 93

Answer:

l : b = 6 : 5

Step-by-step explanation:

let's assume lenght of each congruent rectangle be x

now,

Lenght of the larger rectangle =

=》3 × lenght of smaller rectangle = 3x

but it is also equal to

=》4 × width of each smaller rectangles ( b )

so, we get :-

=》4 × b = 3x

=》b = 3x / 4

so, we get width of smaller rectangle =

$\frac{3x}{4}$

now, width of larger rectangle =

=》lenght of smaller rectangle + (2 × width of smaller rectangle)

=》

$x + 2b$

=》

$x + (2 \times \frac{3x}{4} )$

=》

$x + \frac{3x}{2}$

=》

$\frac{5x}{2}$

now, length of larger rectangle = 3x

width of larger rectangle = 5x/2

so l : w :-

=》

$\frac{3x}{ \frac{5x}{2} }$

=》

$\frac{3 \times 2}{5}$

=》

$\frac{6}{5}$

so, required ratio of l : b = 6 : 5
