Answer:

y = 2(x + 2)² - 7

Step-by-step explanation:

y = 2x² + 8x + 1

= 2x² + 8x + 8 - 8 + 1

= 2(x² + 4x + 4) - 8 + 1

= 2(x + 2)² - 7

Why the following triangles are congruent!

dimaraw [331]

Answer:

Because the sides BO and MA are marked with one line through the middle, which means those sides are congruent, angle A and Angle O are marked with one line, the angles are congruent, and angles W and N are marked with two lines, which means they are congruent. Therefore the triangles are congruent

What the answer question

kobusy [5.1K]

Answer:

$\bold{A_{_{\Delta XYZ}}=927.5\ cm^2}$

Step-by-step explanation:

m∠Z = 180° - 118° - 28° = 34°

$\sin(28^o)\approx0.4695\\\\\sin(118^o)=\sin(180^o-62^o)=\sin62^o\approx0.8829 \\\\\sin(34^o)\approx0.5592\\\\$

$\dfrac{\overline{XY}}{\sin Z}=\dfrac{\overline{YZ}}{\sin X}\\\\\\\overline{XY}=\dfrac{\overline{YZ}}{\sin X}\cdot\sin Z\\\\\\\overline{XY}=\dfrac{42}{0.4695}\cdot0.5592\\\\\overline{XZ}=50.024281...\\\\\\A_{_{\Delta XYZ}}=\frac12\cdot\overline{XY}\cdot\overline{YZ}\cdot\sin(\angle Z)\\\\\\A_{_{\Delta XYZ}}\approx\frac12\cdot50.0243\cdot42\cdot0.8829=927.4955...\approx927.5$
