Step-by-step explanation:

first do the triangle : 11 times 6 divided by 2 equals

the formula for a triangle is base times height divided by 2

now multiply 33 x 2 = 66because there is another triangle at the back.

now do 6 x 8 to find the sides that equal to 48

do 48 x 2 because there are 2 sides

now do the base : 11x8 = 88

for final step add all the answers together

66 + 48 + 88 answer is =

202

PLEASE MARK BRAINLIEST I PUT IN ALOT OF TIME FOR This

Hope it helps :)

Use the zero product property to find the solutions to the equation 2x2 + x – 1 = 2.

FromTheMoon [43]

$2 {x}^{2} + x - 1 = 2$

Subtract sides -2

$2 {x}^{2} + x - 1 - 2 = 2 - 2$

$2 {x}^{2} + x - 3 = 0$

$(x - 1)(2x + 3) = 0$

_________________________________

$x - 1 = 0$

$x = 1$

##############################

$2x + 3 = 0$

$x = - \frac{3}{2} \\$

if you draw 35 lines on a piece of paper so that no two lines are parallel to each other and no three lines are concurrent, how

Levart [38]

Answer:

The lines will intersect 595 times.

Step-by-step explanation:

We can do it in 2 methods.

1st method:- Let us count the number of intersections by drawing lines one by one.

1st line - 0 points=0

2nd line- new 1 point=1

3rd line - old 1 point + new 2 points with two old lines = 1+2

4th line - old (1+2) points+ new 3 points= 1+2+3

5th line - old (1+2+3) points + new 4 points=1+2+3+4

Like that from 35th line-1+2+3+4......34 = $\frac{34X35}{2}=595$

2nd method:-

We have to choose 2 lines from 35 lines.

We can do it in $35_{C} _{2}$ ways = 595 points

How do you simplify 5 plus the square root of 3 squared? <img src="https://tex.z-dn.net/?f=%285%20%2B%20%20%5Csqrt%7B3%7D%29%

blondinia [14]

Use identity -

(a+b)² = a²+b²+2ab

(5+√3)² = 5²+(√3)² + 2(5)(√3)

= 25 + 3 + 10√3

= 28 + 10√3

= 2(14+ 5√3)
