@MyDearest2106 a = +/-10

When a = 10, b^2 = 16
When a = -10, b^2 = 36

@QueenInsight Because BC || DE, this means the outside angle at E is congruent to x and summative to y.

Based on these properties, x + y = 180

@AiWithliza If the two lines with little filled in triangles are parallel, then the angle adjacent to 110 is congruent to x, meaning they equal each other.

Because the angle adjacent to 110 is supplementary, 180 - 110 =70.

So if the lines are parallel, then x = 70

@geniuscyp a = 60

Angle 1, 180 - 140 =40
Angle 2 = 80

a = 180 - 80 - 40=60

@sadafsheriff35 r^2 + r^2 = 2r^2 = 98

r^2 = 49
r = +/- 7

@MathChallengeX Combine the equations and solve for y
2x + 3y = 7
-2x + 2y = -2
____________

5y = 5
y = 1

Solve for x
x - 1 = 1
x = 2

Check the answer:
2(2) + 3(1) =7, yes
2 - 1 =1, yes

@Svm_Sevrae 22, it’s the sum of the 2 digits plus the some of the other 2 digits

@Misssqueeen C = 180 - 150 = 30
B = 180 - A - C = 180 - 40 - 30 = 110
x = 180 - B = 180 - 110 = 70

@mathwithsanni Too easy, thanks Pythagoras

x=sqrt(6^2+8^2)
x=sqrt(36+64)
x=sqrt(100)
x=10

That was easy…now trying to find a square root symbol on an iPhone without using a third party library or copy and pasting for the web…impossible.

@DearGozde The equation is (a + b) + ab

(7+6) + 7*6=55

[Eric @USA_Botox]

This isn’t good math, but looking at the logic it’s the reverse order of the product, the answer is 94

3x3=9, only one digit, so nothing to reverse

4 * 4 =16, in reverse is 61

5 * 5=25, in reverse 52

6 * 6=36, in reverse 63

7 * 7=49, in reverse 94

I don’t like this one though

@liadreaamy 9

[Eric @USA_Botox]

@Rhee_10 40

It’s the product of the two numbers plus 5, So 7 * 5 + 5=40

[Eric @USA_Botox]

@batuhanppn 50.

5 + 3 =8
8 + 2*3=14
14 + 2*6 =26
26 + 2*12=50

[Eric @USA_Botox]

@Freya_24mU The answer is 8 or -2.

4y^2= 100
y^2=25
y= +/- 5

y + 3 = ?

Substitute +/- 5

5 + 3 =8

-5 + 3 =-2

[Eric @USA_Botox]

@farman4x Looks like the equation for the logic is a^2* b, so 4^2*6=96

[Eric @USA_Botox]

@bronco2120 @uh__yeah @lunadreaamy When you substitute -8…

-8 x -8 - (-8) = 64 + 8 = 72, so the answer was correct
