Answer:
y=-6x-2
Step-by-step explanation:
Answer:
x=
Step-by-step explanation:
First, we need to solve the angle inside the triangle. That would be 55+40+angle measure=180
angle measure=85°
Now that we know that, we can solve for x by setting 85-3x-18 equal to 180° because these two values form a linear pair which is 180°.
Let's use some simple algebra to solve for x:
85-3x-18=180
67-3x=180
-3x=113
x= or about -37.67
Hope this helps!! :)
For the zero product property questions it's choices 2 and 3 since they're quadratics factored and set equal to zero.
for the quadratic formula questions it would be answer choices 2 and 3 also because they're unfactored trinomial quadratic expressions
Answer:
volume= 1040
surface area=696
Step-by-step explanation:
1/2x 13x10x16
=1040#
(1/2x12x10)2
=120
(16x13)2
=416
16x10
=160
120+426+160
=696#
Answer:
3(x + 8) = 6
Step-by-step explanation:
let the number be x then the sum of x and 8 is x + 8 and multiplied by 3 is
3(x + 8) = 6 ( divide both sides by 3 )
x + 8 = 2 ( subtract 8 from both sides )
x = - 6
the number x is - 6
