G(x) = (x+2)(x+3), this is from factoring then replace x with -4 and the equation should look like this g(-4)-7= (-4+2)(-4+3)-7= -5,
Answer:
196
Step-by-step explanation:
1+2+3+4+......+25+26+27 = (1+27) + (3+25) + (5+23)+(7+21) + (9+19) + (11+17) + (13+15)
= 28 x 7 = 196
It's like area of trapezoid of bases: 1, 27 and height of 14
Answer:
<h2>15</h2>
Step-by-step explanation:
∠6 and ∠7 are Alternate Interior Angles.
The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.
m∠6 = m∠7 → 4x - 15 = x + 30 <em>add 15 to both sides</em>
4x = x + 45 <em>subract x from both sides</em>
3x = 45 <em>divide both sides by 3</em>
x = 15
