Answer:

4925cm^2

Step-by-step explanation:

whole thing - small thing = shaded

small = 25 x 25 = 625

whole thing = a+b / 2 x h     =    111+111/2 x 50 = 5550

5550-625= 4925cm^2

A line passes through points (-4, -19) and (-6, 4). what is the equation of the line written in slope-intercept form?
BabaBlast [244]
The equation of the line written in slope-intercept form is:

y = mx + b
Where m is the slope and b is the y-intercept.
You find the slope using the formula:

m =  \frac{yb - ya}{xb - xa}
Where point A coordinates' are (-4,-19) and point B (-6, 4).

m =  \frac{4 + 19}{ - 6 + 4}
m =  -  \frac{23}{2}
Now you find b (y-intercept) substituting in y=-23/2x+b the coordinates of point A or point B:
(I'll use point B coordinates')
y=-23/2x+b
4=-23/2×(-6)+b
4=46+b
b=-42
The equation of the line is y=-23/2x-42

Which is a solution to the equation? (x −2)(x + 5) = 18 x = −10 x = −7 x = −4 x = −2
Leona [35]

Answer:

Solutions:

x=-7

x=4

Step-by-step explanation:

(x-2)(x + 5) = 18

Expanding the factored form:

x^2+5x-2x-10=18

x^2+3x-28=0

Factoring the second-degree polynomial:

(x+7)(x-4)=0

This is true for

x=-7 \text{ or } x=4

What is the value of x in the equation 1.5(x + 4) - 3 = 4.5(x - 2)?
padilas [110]

Answer:4

Step-by-step explanation:

First distributive 1.5 to x+4 and 4.5 to x-2. You get 1.5x+6-3 = 4.5x-9. Next you need to move all the variable terms to one side. You can do either, it doesn't matter, but I subtracted 1.5 x to each side of the equation. You get left with 6-3 = 3x-9. Solve 6-3 and you get 3=3x-9. You 9 to both sides of the equation. You get 12=3x. You divide by 3 on both sides and get 4=x/x=4.
