Answer:
7786
Step-by-step explanation:
8753-967
=7786
4(6x+4)-5(3x-6) First you distribute 24x+16-15x+30 then you add like terms so 24x-15x is 9x. 16+30 is 46. So the answer is 9x+46
Answer:
32, 36, 40
Step-by-step explanation:
8x + 9x + 10x = 108
27x = 108
x = 4
4 × 8 = 32 - 1st side
4 × 9 = 36 - 2nd side
4 × 10 = 40 - 3rd side
5x^2-45=0
<em>*Add 45 to both sides*</em>
5x^2=45
<em>*Divide both sides by 5*</em>
x^2=9
<em>*Take the square root of both sides*</em>
x=+/-9
Hope this helps!!
