X^2 + 8x + 7 = 0
x^2 + 7x + x + 7 = 0
x(x + 7) + 1(x + 7) = 0
(x + 7) (x + 1) = 0
x = -7 or x = -1
The total is 275 because 100% divided by 20% is 5 and if 20%= 55 then that means that 55 goes into 100% 5 times so you multiply 55 by 5 to get 275. Hope I helped! Please rate me as the brainliest!

First of all option C and D are ruled out because no area is shaded. Because the values of Y are all ≥ 1 - 3x the area shaded should be above the line and the line should not be dotted, it should be a full line. Although there seems to be no option for both a full line and above the line is shaded.

Triangles DEF and JKL can be proven to be congruent triangles based on:
C. ASA
E. AAS
F. LA
<h3>What is the ASA Congruence Theorem?</h3>
The ASA congruence theorem states that if two triangles that are have two pairs of corresponding congruent angles and a pair of corresponding included congruent sides, then both triangles are congruent to each other.
<h3>What is the
LA Congruence Theorem?</h3>
The LA congruence theorem states that two right triangles are congruent if they have a pair of congruent legs and a pair of congruent angles that are corresponding to each other.
<h3>What is the AAS Congruence Theorem?</h3>
The AAS congruence theorem states that two triangles with two pairs of congruent angles and a pair of congruent non-included sides are congruent.
From the image given, triangles DEF and JKL can be proven to be congruent triangles using the LA, AAS, and ASA congruence theorems.
