Step-by-step explanation:
7*3y - 7*5 + 2*4y + 12
= 21y - 35 + 8y + 6
= 29y - 29
= 29(y-1)
Exactly the same three sides and
exactly the same three angles
Answer:
x = -2
Step-by-step explanation:
3(5x + 2) = 2(3x - 6)
<em>Expand the brackets. </em>
15x + 6 = 6x - 12
<em>Isolate the unknown variable x. </em>
15x - 6x = -12 - 6
<em>Evaluate. </em>
9x = -18
<em>Find x. </em>
x = -18 ÷ 9
x = -2
Answer:
The sale price will be 143.20
Step-by-step explanation:
20% of 179 is 35.80
179 - 35.80 = 143.20
Since sides kl and kj are congruent that means that angles klj and kjl are congruent. if angle klj is 58 then that means kjl is also 58. so you take the total number of degrees in a triangle (180) and subtract 58 and 58 (116) which leaves you with 64 ( the degree measure of lkj)
