Lorico [155]

Answer:

Step-by-step explanation:

negative 78 squared = -6084

-6084 + 3 - 9 = -6090

-6090 - 5 squared minus 6 minus 4 = --6125

I got confused by "8th" and "a minus" do you mean 3a, and 6a?

Polynomial help! 40 pts, please show all work for question 49 part a and b
hoa [83]

Answer:

4x^2 +84x+440

840 in^2

Step-by-step explanation:

The length of the picture and frame is x+ 22+x= 2x+22

The width of the picture and frame is x +20+x = 2x+20

Area is length times width

A = (2x+22) *(2x+20)

We can FOIL to find the area

first 2x*2x = 4x^2

outer 2x*20 =40x

inner 2x*22 = 44x

last = 22*20 = 440

Add these together

4x^2 +40x+44x+440

4x^2 +84x+440

b.  x=4

4x^2 +84x+440

4(4)^2 +84(4) +440

4*16 +336+440

64+776

840

PLEASE IM BEGGING YOU HELP ME! ITS DUE SOON PLEASE ACTUALLY SHOW YOUR WORK :(( SOMEONE PLEASE OMG HELP NO ONES HELPING ME UGHHHH
anyanavicka [17]

Answer:

x=0, y=-12

Step-by-step explanation:

you can use substitution to solve for x

-3(x-12)=2x+36

-3x+36=2x+36

subtract 36 from both sides and add 3x to both sides

0=5x

x=0

now plug in 0 as x for either equation

y=0-12

y=-12

to check your work plug in x and y into the other equation

-3(-12)=2(0)+36

36=36

Two angles are complementary. If one angle is 4 times larger than other one then what is the measure of the smaller
arlik [135]

Answer:

The smaller angle is 18 degrees

The larger angle is 72 degrees

Step-by-step explanation:

x = smaller angle

y = larger angle

y = 4x ---> one angle is 4 times larger than other one.

y + x = 90 ----> the sum of complementary angles is 90 degrees

4x + x = 90 ----> plug in 4x for the larger angle (y) and then solve

5x = 90

x = 18 ----> the smaller angle is 18 degrees

y = 90 - 18

y = 72 ----> the larger angle is 72 degrees
