Answer:

1. rectangles and triangles

2. 63 m²

Step-by-step explanation:

1. The figure is composed of one rectangle on top and one triangle on the bottom

2. To find the area of the rectangle, we need to use the formula A = b×h

Here the base is 9 and the height is 7
Substituting these values into the formula we get A = (9)(7) = 63 m²

In ABC the measure of angle a is 2X +3 the measure of angle B is 4X +2 and the measure of angle C is 2X-1 what are the measures

Novay_Z [31]

Angle A is 2x + 3
Angle B is 4x + 2
Angle C is 2x - 1

The three angles add up to 180
So:
2x + 3 + 4x + 2 + 2x - 1 = 180
Combine terms
8x + 4 = 180
Subtract 4
8x = 176
x = 22

Now we solve for the angles:
Angle A is 2(22) + 3 = 44 + 3 = 47
Angle B is 4(22) + 2 = 88 + 2 = 90
Angle C is 2(22) - 1 = 44 - 1 = 43

Quick check: 47 + 90 + 43 = 180

Give the first 4 terms of a sequence who has the explicit formula an = 4n – 13

andreev551 [17]

Step-by-step explanation:

from,

An = 4n -13

A1 = 4 (1) - 13

> A1 = -9

A2 = 4(2) - 13

> A2 = -5

A3 = 4(3) - 13

> A3 = -1

A4 = 4(4) - 13

> A4 = 3

<h3>✒️EVALUATION </h3>

==================================

$\large\sf\underline{Problem:}$

What is the product of (2x-7) and (3x + 3)?

A. 6x2 + 15x-21
B. 6x2 - 15x - 21
C. 6x2 + 15x + 21
D. 6x2 - 15x + 21

==================================

$\large\sf\underline{Answer:}$

$\qquad \qquad \huge \rm Letter\:B.$

*Please read and understand my solution. Don't just rely on my direct answer*

==================================

$\large\sf\underline{Solution:}$

Here we have the given choices:

A. 6x2 + 15x-21
B. 6x2 - 15x - 21
C. 6x2 + 15x + 21
D. 6x2 - 15x + 21

Solve this equation using the distributive property,where you multiply each term to get the number.

$\begin{gathered} \rm2x - 7 = \boxed{ 6} \: \bigg| \small\boxed{\: 6 {x}^{2} } \\ \rm (7)(3) = \boxed{21} \bigg | \boxed{\: 21 x} \\ \\ \qquad \rm6x^{2}+(6x- 21x)-21 \\ \qquad \boxed{ \rm6 {x}^{2} + 15x - 21}\end{gathered}$
