How would you describe slope for a school assignment in 4 sentences or more?

8 0

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Sometimes the ratio is expressed as a quotient ("rise over run"), giving the same number for every two distinct points on the same line. A line that is decreasing has a negative "rise". The line may be practical - as set by a road surveyor, or in a diagram that models a road or a roof either as a description or as a plan.

Factor of 4-(2a+3b)^2

Anna71 [15]

$4-(2a+3b)^2$

$(2a+3b)^2 :$

$4a^2+12ab+9b^2$

$= 4-(4a^3+12ab+9b^2)$

$=-(4a^2)-(12ab)-(9b^2)$

apply minus - plus rules :

$+(-a)=-a$

Refine:

$=-4-4a^2-12ab-9b^2$

Please answer 4 - 9 will mark brainlyist

miv72 [106K]

There are 180 degrees in a triangle

4. 38+38= 76 degrees

180-76=104

Isosceles, Obtuse

5. 65+ x+x=65

Well we know one of the x

It is 90 degrees because it is a right angle

65+90=155

180-155=25

Scalene, Right triangle

6. 71+45= 116

180-116=64

7. Scalene, acute

8. 126+22=148

180-148=32

Scalene, Obtuse

9. 50+90=140

180-140=40

Right angle, Scalene

Please let me know if i got anything wrong

six girls and four boys have entered the science fair. first, second, and third place awards are to be given out. what is the pr

Dafna1 [17]

Given:
6 girls
4 boys

Probability of 1 girl being chosen: 1/6
Probability of 1 boy being chosen: 1/4
Probability of another boy being chosen: 1/3

1/6 = 0.17 x 100% = 17%
1/4 = 0.25 x 100% = 25%
1/3 = 0.33 x 100% = 33%

17% + 25% + 33% = 75%

The probability that exactly one girl and two boys will receive awards is 75%.
