(2r - 6)(-5r+4) what is the product

Akimi4 [234]

Answer:

$-10r^{2} +38r-24$

Step-by-step explanation:

Apply FOIL method: $(a+b)(c+d)=ac+ad+bc+bd$

$a=2r,b=-6,c=-5r,d=4$

$=2r(5-r)+2r*4+(-6)(-5r)+(-6)*4$

Apply minus - plus rules

$+(-a)=-a,(-a)(-b)=ab$

$=-2*5rr+2*4r+6*5r-6*4$

Simplify

Multiply $-2*5rr=-10r^{2}$

$=-10r^{2} +2*4r+6*5r-6*4$

Multiply $2*4r=8r$

$=-10r^{2} +8r+6*5r-6*4$

Multiply $6*5r=30r$

$=-10r^{2} +8r+30r-6*4$

Combine like terms

$=-10r^{2} +38r-6*4$

Multiply $-6*4=-24$

$=-10r^{2} +38r-24$

$-10r^{2} +38r-24$

How can you solve the literal equation y-3x=13

ser-zykov [4K]

So to begin, you need to find x and y. If you have answer options, plug those in. If you don't, your toast. Just kidding :)
So, your answer would be y3=13. I think you can handle the rest. 3 * what equals 13?

Parker drew a triangle with no cogruent sides and a 95° angle. Classify the triangle by the lengths of its sides and measures of

Alika [10]

Obtuse scalene, because none of the side are equal ( which would make none of the angles equal), but the one angle is over 90°

Need help please and thank you

Georgia [21]

Answer:

y=5

x=20 degrees

K= 43 degrees

L=137 degrees

Step-by-step explanation:

aducent angles of parralologram add to 180 degrees

so (6x+17)+ (2x+3)=180

or 6x+17+2x+3=180

so 8x+20=180

and 8x=160

x=20 degrees

opposite sides of parralologram are equal so

6y-13= 32-3y

or 9y=45

and y=5

opposite angles are coonguent so

ang K= 2x+3

so K= 43 degrees

aducent angles of parralologram add to 180 degrees

so ang L+43=180

and L=137 degrees
