Think of the square as a rhombus:
$\frac{15 \times 15}{2} = \frac{225}{2} = 225 \div 2 = 112.5$
so 112.5 square inches

you can ask if it wasn't clear enough, I will explain.
Have a nice day!!!!

(2x/3)-(5x/9)-(x/6)-(5x/12)=13/2 this equation is equivalent to:

agasfer [191]

Answer:

-17x=234

Step-by-step explanation:

Given that:

$\dfrac{2x}{3}-\dfrac{5x}{9}-\dfrac{x}{6}-\dfrac{5x}{12}=\dfrac{13}{2}$

$\dfrac{72x-60x -18x-45x }{108} = \dfrac{13}{2}$

$\dfrac{-51x }{108} = \dfrac{13}{2}$

$-102x = 1404$

$-\dfrac{102x}{6} = \dfrac{1404}{6}$

-17x = 234

Xiao's teacher asked him to rewrite the sum 60+90 the product of the GCF of the two numbers and a sum. Axial wrote 3(20+30). Wha

LuckyWell [14K]

60 + 90

GCF = 30

(30 * 2) + (30 * 3) = 30(2 + 3) <== the correct way

The mistake Axial made was he did not pick the greatest common factor...he picked 3 instead of 30.

Simplify

Scorpion4ik [409]

Answer:

Step-by-step explanation:

using the rule of exponents

$(\frac{a}{b}) ^{-1}$ = $\frac{b}{a}$ , then

$\frac{123}{321}$ × $\frac{456}{654}$ × $\frac{789}{987}$ × $\frac{321}{123}$ × $\frac{654}{456}$ × $\frac{987}{789}$

[ $\frac{123}{321}$ × $\frac{321}{123}$ = 1 , $\frac{456}{654}$ × $\frac{654}{456}$ = 1 , $\frac{789}{987}$ × $\frac{987}{789}$ = 1 ]

= 1 × 1 × 1

= 1

Y-intercept, where the graph crosses y-axiss is 0. that means in the equation: y = mx + b
b = 0
the m, is slope. looking at the graph you can see the points on the line are connect up 4 right 1. rise/run = slope = 4
