Well, if 4 muffins cost $5.24, then we can do 5.24 ÷ 4 = 1.31 to know that one muffin costs 1.31. Now we can do 1.31 x 5 = 6.55 to know 5 muffins cost 6.55.

Use either the square of a binomial or the

notsponge [240]

Answer:

9. 2916 sq. cm

10. 864 sq. in

Step-by-step explanation:

9.) 54 cm * 54 cm = area of square

(50 + 4)*(50 + 4) = 50*50 + 8*50 + 16

= 2500 + 400 + 16 = 2916 sq cm.

10. 24 in * 36 in. = area of rectangle

get: (30 - 6)*(30 + 6) = 30^2- 6^2

= 900 - 36 = 864 sq. in.

Provide the reasons for the fol owing proof

Answer:

Option d is correct.

Vertical angles are congruent;

SAS

Step-by-step explanation:

Given: $JK \cong KL$ , $NK \cong KM$

In ΔNKJ and ΔMLK

$JK \cong KL$ and [Side] {Given}

$NK \cong KM$

Vertical angles states that the two lines intersect to make an X, angles on opposite sides of the X are called vertical angles.

i.e $\angle NKJ$ and $\angle MKL$ are vertical angles.

Also, vertical angles are congruent.

$\angle NKJ \cong \angle MKL$ [Angle] [Vertical angles are congruent]

SAS(Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

then, by SAS postulates;

$\triangle NKJ \cong \triangle MLK$ Hence proved!
