Answer: c

use distributive property:
2(a+6)-3(a-5)+15=18
2a+12-3a+15=18

combine like terms:
2a+12-3a+15=18
-a+27=18

Simplify (7^5)^3<br> A.7^8<br> B.(1/7)^15<br> C.35^3<br> D.7^15

oksano4ka [1.4K]

Answer:

$\red{{7}^{15} }$

Step-by-step explanation:

We know that,

${x}^{a} \times {x}^{b} = {x}^{a + b} \\ ( {x}^{a} ) ^{b} = {x}^{ab}$

Accordingly,

$( {7}^{5} ) ^{3} \\ {7}^{5 \times 3} \\ {7}^{15}$

Two angle of a tranigle measure 55 and 20 what is the measure of the third angle

wariber [46]

Answer:

105 degrees

Step-by-step explanation:

Recall that the sum of angles in a triangle is 180 degrees. As such, where a, b and c are the angles of a triangle then

a + b + c = 180 ( all in degrees)

Given that two angles of a triangle measure 55 and 20, let the size of gthe 3rd be T then

55 + 20 + T = 180

simplify

75 + T = 180

Subtract 75 from both sides

T = 180 - 75

T = 105

A sign company charges $28 per yard for each custom made banner. Ms. Gill orders two banners that are each 1 7/8 yards yards lon

Svetlanka [38]

Answer:

$896

Step-by-step explanation:

We are given that

Charge of 1 yard for each custom-made banner=$28

Length of 1 piece=15 yards

Length of another piece=2 yards

We have to find that how much money payed by Ms.Gill for all three banners.

According to question

Cost of 15 yards long banner=$420

Cost of 2 piece of 15 yards long banner==$840

Cost of 2 yards long banner==$56

Total cost of 3 piece of banners=840+56=$896

Hence, Ms gill pay for all three banners=$896

You plot these 4 points on the coordinate plane then you move 4 units to the right and 3 units down for each point and then you figure out the points of W'K'L'X BY looking at where it ended up
