Answer: 27x²yz + 3xz² - 2xy - 2y²z + 2yz²
<u>Step-by-step explanation:</u>
Use the distributive property.
3xz(9xy + z) - 2yz(x + y - z)
= 3xz(9xy) + 3xz(z) -2yz(x) -2yz(y) -2yz(-z)
= 27x²yz + 3xz² -2xy -2y²z +2yz²
Answer:
12x-8
Step-by-step explanation:
Added both equations and used PEMDAS to combine all equations
to find the value of x, you have to subtract 95 from 180. so the value of x will be 85. to find the value of y, you have to add the value of x which is 85 to the given angle which is 50. the angle would be 135. since the triangle is 180 degree, now u subtract 135 from 180. and the value of y will be 45. so x is 85 degree and y is 45 degree. hope that helps.
Answer:
x = 33
Step-by-step explanation:
these two angles are a linear pair, they form a straight line
there are 180 degrees in a straight line
so you can add each expression and have sum equal 180
2x-18 + 4x = 180
6x - 18 = 180
6x = 198
x = 33
Answer:
yes 80 is a multiple of 4 because 4 × 20 = 80
