$\sf are a \ of \ triangle : \frac{1}{2}*base *height$

$\sf are a \ of \ rectangle : Length * Width$

total area :

$\sf are a \ of \ rectangle + area \ of \ triangle$

$\rightarrow \sf 9 * 10 + \frac{1}{2} *8.5*10$

$\rightarrow \sf 132.5 \ in^2$

Factor completely. 12x4+18x3+45x2 Enter your answer in the box.

QUESTION 1

The given expression is

$12x^4+18x^3+45x^2$

The greatest common factor is $3x^2$ .

We factor to obtain;

$3x^2(4x^2+6x+15)$

QUESTION 2

The given quadratic equation is

$x^2+6x-72=0$

We split the middle term to obtain

$x^2+12x-6x-72=0$

Factor by grouping;

$x(x+12)-6(x+12)=0$

$(x+12)(x-6)=0$

Use zero product property;

$(x+12)=0\:\:or\:\:(x-6)=0$

$x=-12\:\:or\:\:x=6$

QUESTION 3

The given system of equation is

$3x+4y=-8$

$7x-3y=6$

If we multiply $3x+4y=-8$ by 3, we obtain;

$9x+12y=-24$

If we multiply $7x-3y=6$ by 4 we obtain;

$28x-12y=24$

Adding the last two equations will give us;

$37x=0$

The y-variable is eliminated.

Answer:Multiply 3x+4y=−8

by 3. Multiply 7x−3y=6 by 4. Add the resulting equations together.

Help plz i’ll give extra points : )

Answer:

y = 6/5x - 24/5

Step-by-step explanation:

The two points we are given are (4, 0) and (9, 6). First, find the slope.

m = 6 - 0/9 - 4 = 6/5

Next, insert the values into the point-slope form formula. I'll use (4, 0) as the coordinates.

y - 0 = 6/5(x - 4)

y = 6/5x - 24/5
